DARPA ENVision developing next-generation Night Vision Goggles (NVGs) which are compact, multi-band, and wide-FOV

For decades U.S. warfighters have benefitted from advanced night-vision technology, allowing pilots to fly low-level missions on pitch-black nights and ground forces to conduct operations against adversaries in the dark. Traditional Night Vision Goggle (NVG) systems provide the wearer with enhanced visibility in low-light conditions by exploiting the natural near-infrared …

DARPA plans Laser-based wireless power transmission network on Battlefield

Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, a transmitter device, driven by electric power from a power source, generates a time-varying electromagnetic field, which …

Semiconductor lasers

The essential components of a laser are an external energy source, a gain or amplifier medium, and a resonator. When a medium, for example an Nd:YAG crystal is arranged so between two mirrors that photons always trigger an “induced emission”, this is called an optical resonator. Semiconductor lasers are solid-state lasers …

CubeSat cameras and optical payloads for Earth Observation small satellites

Constellations of satellites are being proposed in large numbers; most of them are expected to be in orbit within the next decade. They will provide communication to unserved and underserved communities, enable global monitoring of Earth and enhance space observation.   In a Low Earth Orbit (LEO), a satellite completes about …

Nano-opto-electro-mechanical systems (NOEMS)

Modern microelectronic semiconductors and integrated circuits provide remarkable computational and memory capabilities but lack the capability to interface with the physical world directly. MEMS (MicroElectroMechanical Systems) and the even smaller NEMS (Nano ElectroMechanical Systems)  integrate sensors and actuators on microelectronic circuitry and enabling these products, awareness of the surroundings in …

Liquid crystal on silicon (LCoS or LCOS)

Flat-panel display technology is exploding on several fronts as more screens are required for more devices. CRT still works well for screen sizes up to 40 inches. But if you want a larger screen, a flat panel TV, widescreen model or HDTV compatibility, you’ll have to choose from several types …

Infrared detectors enable Night Vision Devices, Robotic servicing mission to military missile tracking

Remote sensing is the science of acquiring information about the Earth’s surface without actually being in contact with it.  This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Some examples of remote sensing are special cameras on satellites and airplanes taking …

Thermal imaging camera technologies image hidden targets from far in complete darkness through fog or smoke

Thermal vision cameras make pictures or video from heat, not visible light. Heat (infrared thermal radiation) and light are both parts of the electromagnetic spectrum. Thermal cameras detect more than just heat. Heat vision cameras detect the tiny differences in heat, even as small as 0.01° Celsius.   All objects warmer than …

New laser materials that would yield smaller, more powerful lasers with broad tunability.

The essential components of a laser are an external energy source, a gain or amplifier medium, and a resonator. When a medium, for example an Nd:YAG crystal is arranged so between two mirrors that photons always trigger an “induced emission”, this is called an optical resonator. The supply of external …

Emerging ultrashort pulse laser (USPL) or Femtosecond laser directed energy weapons (DEW)

The Laser Directed Energy Weapons (DEWs) offer a transformational ‘game changer’ to counter asymmetric and disruptive threats, while facing increasingly sophisticated traditional challenges. Laser technology provides major advantages for military applications over kinetic weapons due to High precision and rapid on-target effect, precise and scalable effects,  avoidance of collateral damage …
