Electro-optical or EO systems refer to devices that make use of a mix of optics and electronics for generating, detecting and measuring radiation in the optical spectrum. The systems can measure electromagnetic spectrum with wavelengths in the 0.1-1000 micrometers range, which comprises visible light, infrared radiation and ultraviolet radiation.
An electro-optical sensor is capable of changing light into electric signal, while the infrared sensor can identify any structure in its vicinity through the detection or emission of infrared radiation. Common applications of EO/IR systems include airborne homeland security, combat, patrol, surveillance, reconnaissance, and search and rescue programs.
EO/IR (Electro-Optical/Infra-Red) systems are imaging systems used for military or law enforcement applications which include both visible and infrared sensors. Because they span both visible and infrared wavelengths, EO/IR systems provide total situational awareness both day and night and in low light conditions.
The increasing focus on information superiority by militaries and situational awareness is leading to the procurement of military electro-optical/infrared (EO/IR) systems worldwide. Additionally, the increased demand for battlespace reconnaissance and greater adoption on airborne platforms such as unmanned aerial vehicles (UAV), fighter aircrafts, helicopters, among others are the major factors driving the military electro-optics/infrared systems market, says GlobalData, a leading data and analytics company.
Major features of the systems include image stabilization and long-range imaging capabilities. Critical features of EO/IR systems are long-range imaging abilities and image stabilization. EO/IR sensors are usually mounted on aircraft or vehicles, used at sea, or are hand-carried, and must be able to identify targets, track moving targets, and assess threats from a distance and in challenging environmental conditions.
Electro-optical and infrared (EO/IR) systems are largely used for military applications in airborne, land-based, and naval platforms. Airborne EO/IR systems comprise optic sights, night vision systems inspection systems, and helmet-mounted displays. Land-based systems include weapon mounted sights, optronic devices, night vision devices, thermal imagers, designators, and laser range finders. Naval based systems consist of infrared imagers and detectors, thermal imagery systems, surveillance & tracking systems, and photonics mast systems.
Nowadays, long-wave infrared (LWIR) systems are most commonly integrated with military systems to provide advanced thermal imaging capacities and improved target detection and recognition. In low light conditions, night vision cameras are used for better performance with less power consumption and optimum output. Moreover, laser range finders are also used in both day or night conditions and in nearly all weather conditions, including haze, smoke, and rain.
Developments in electro-optical (EO) and infrared (IR) systems are key to providing the enhanced capability needed by military forces to meet the current and emerging challenges created through an increasingly difficult and complex range of operational conditions. Such enhanced operational capability must often be delivered against commercial demands for lower costs and reduced timescales together with operational requirements for size weight, and power (SWaP) reductions.
Moreover, defense agencies across the globe are strengthening their position with huge investments in the development of new technology and systems. For example, the development of indium gallium arsenide (InGaAs) detector system allows imaging in short-wave infrared (SWIR) without the necessity of an external cooling system. In addition, it also consumes less power and delivers images at high frame rates. It also offers real-time detection during the day or low light conditions. Thus, such technological advancements are driving the growth of the military EO/IR systems market.
Furthermore, the adoption of new technologies such as LWIR system by the military forces provide armored vehicles with advanced thermal imaging capacities and improved target detection, recognition, and identification of the range. In addition, the imaging capability provides actionable information and crew protection in the war conditions. Likewise, the usage of EO laser guidance systems has been increasing for special military missions. This system has an imaging camera, which acts as a sight and target seeker for small weapons and missile systems. Also, it is a cost-effective and lightweight with highly accurate solutions for target acquisition and weapon guidance.
Low C-SWaP EO/IR ISR Sensor Technology
The goal is to develop low-cost, size, weight, and power (C-SWaP) Electro-Optical Infra-Red (EO/IR) sensor technology to support distributed intelligence, surveillance and reconnaissance (ISR) in contested environments (CEs). Future engagements may necessitate operations in CEs, putting high-value platforms and associated sensors at risk. As such, future missions may utilize lower-cost, attributable platforms to support operations in CEs. Associated ISR sensor technology is required for such platforms where C-SWaP constraints are more significant than for traditional platforms. Technology advancement is required in many sensor modalities, including, but not limited to broadband EO/IR, multispectral, hyperspectral, polarimetric, and LIDAR. Research and development can include full system-level designs or advancement of component technology, such as detector materials, telescopes, transmitters, receivers, real-time data processing hardware, etc
EO and IR systems are likely to benefit from recent advances in material research, for example new carbon-based materials, nano-materials and metamaterials. These new materials promise new EO properties that could significantly change the way EO and IR systems are designed and built, e.g. new detector systems with enhanced properties or negative refractive index materials which could radically change the way optics are designed.
The performance challenges faced by future military systems will continue to evolve and grow. To address these challenges, EO/IR system designers will need to draw upon the ongoing developments in underpinning technologies such as new materials, focal plane arrays, image processing, data fusion, and emergent sensor concepts such as spectral processing, computational imaging, and polarimetry. Modelling and simulation is increasingly becoming an enabler for maximizing performance and optimizing operational adaptability and its interaction with trials and validation is a subject of topical concern.
Advanced technology by itself is not sufficient to give new and/or advanced capabilities. Systems have to be designed and developed in a way that will enable their reliable and cost-effective manufacture. This will involve adopting rigorous development and system engineering techniques. These are as crucial for the successful exploitation of sensor technology as the detector, optics and electronics. The performance and required characteristics of sensor systems are critically dependent on the platform and the application. Many sensor payloads are now being fitted to autonomous vehicles and drones which present new challenges in design and integration. Applications areas that are currently receiving interest include target detection and tracking, area monitoring, mine and IED detection, environmental monitoring, and border security. There is also growing interest in wearable imaging devices which have their own unique challenges at the sensor designlevel, the exploitation of the sensor data, and the interconnection of multiple sensors.
SpaceX to explore ways to provide weather data to U.S. military
Charlotte Gerhart, chief of the Space and Missile Systems Center Production Corps Low Earth Orbit Division, said in a statement to SpaceNews that SpaceX received the contract in July 2020 from SMC’s Space Enterprise Consortium. The contract is to “assess the feasibility and long term viability of a ‘weather data as a service business model,’” said Gerhart.
The contract awarded to SpaceX is part of a Space Force program called Electro Optical/Infrared Weather System (EO/IR EWS). The consortium in June awarded $309 million in contracts to Raytheon Technologies, General Atomics Electromagnetic Systems, and Atmospheric & Space Technology Research Associates to develop weather satellite prototypes and payloads. SpaceX won the portion of the EO/IR EWS program that is looking at how weather data could be purchased as a service from a commercial company. “The EWS program goal remains to provide a more resilient and higher refresh capability, enhancing global terrestrial weather capability,” said Gerhart.
“The Air Force is pursuing a space-based environmental monitoring EO/IR system in a multi phased approach,” the SpEC said in an email to members. The EO/IR EWS program is looking at a future proliferated low-Earth orbit constellation to focus on cloud characterization and theater weather imagery that could be supplemented by commercial services. SpaceX’s contract is for the “weather data as a service system architecture exploration phase,” said SpEC. Industry sources speculated that SpaceX could provide weather data collected by sensors hosted on its own Starlink satellites, or it could team with a weather data services company and use Starlink to distribute the data to customers.
Computational Imaging, e.g. Pupil Plane Encoding, Coded Aperture Imaging, Compressive Imaging, etc, is another family of emerging technologies that will radically alter the way sensor systems are designed. These techniques combine optics and processing to provide a useable output from the sensor and can provide functionality not possible or practical with conventional system designs. Computational Imaging will require developments in specialist sub-components, non-standard optics design and algorithm development to reconstruct the image.
Quantum techniques are also being investigated to assess their potential for sensing systems. Quantum Imaging and Ghost Imaging are examples of quantum techniques being investigated by different teams. Any Quantum system will require specialist components e.g. sources, optics, detectors, electronics and processing as well as providing scope for unconventional system design. Processing of sensor information has become a vital component of EO/IR sensor systems for display-driven, semi-autonomous, and autonomous applications. The timely extraction and presentation of pertinent information in a usable format is the ultimate goal in most developments, although the design flexibility to support hardware upgrades and meet emergent operational needs must be considered. Dual and multi-sensor system designs provide additional information, and offer increased performance under a wider variety of conditions. The combination of such sensor information to provide both increased performance and robustness continues to present many design challenges despite the ongoing research into data fusion technology.

Europe today stands testimony to the massive human and economic losses suffered due to an unprepared healthcare system and political underestimation of COVID-19 in terms of the propensity of the disease to spread and cause harm and its ability to bring businesses and whole economies to a halt. Germany which is already in recession is looking towards defense as the first government areas to be wrung for savings. The downsizing will mean delays in defense capabilities improvements. In addition, the COVID-19 pandemic has disrupted supply chains causing massive damage for manufacturing companies reliant on China for supplies. These supply chain disruptions will step up the pressure to decouple from China.
Rethinking supply chains will spur the movement of production out of China, including defense products and raw materials for producing these products. Currently, China is the low cost producer and thousands of defense related equipment and products used by the U.S. comes from this country. Production shifts away from China means DoD procurement and sustainment costs will rise in the coming years. Under this scenario, even without budgetary cuts, the ability to purchase defense products and technologies will fall, and with spending cutbacks being inevitable its hard times ahead for all players in the defense supply chain.
Asia-Pacific region is expected to generate the highest demand for military electro-optical and infrared systems market during the forecast period. With the hike in military spending of some of the countries in the region along with increasing territorial issues, the armed forces in this region are now investing heavily in soldier modernization and equipment modernization programs. Soldier modernization programs are a major driver for the military electro-optics/infrared (EO/IR) systems market in Asia-Pacific. Asia-Pacific is estimated to lead the military electro-optics/infrared (EO/IR) systems market. China, India, Japan, and Australia are the major countries that offer growth potential for EO/IR systems in the Asia-Pacific region. This market has huge growth potential given the increasing demand for updated and technologically advanced optronics systems. The growth of electro-optics/infrared (EO/IR) systems market is also driven by the rising demand for systems equipped with laser technology.
