Laser attacks targeting pilots and air crews are a major concern across the world with most attacks reported to take place during take-off and landing. According to figures from the US Federal Aviation Authority, there were 6,753 laser illuminations reported in 2017. Until recently, the expense of lasers had limited their use …

The  drones have emerged as a major new threat to civilian infrastructure and military.  The militant organizations have started employing drones to further their terrorism. Jihadi groups fighting the Syrian government – most notably ISIS and Jabhet al-Nusra – are extensively using advanced drones to pinpoint the Syrian Army’s locations, …

Smartphone camera technology is growing in leaps and bounds in the past couple of years and continues to be a major point to differentiate their products. The commercial development of curved image sensors is one of the biggest advance in camera technology in decades, allowing for simpler, flatter lenses with …

Researchers have looked into nature for inspiration, understanding the mechanisms animals, insects and plants use to capture and process light and then designing next generation optoelectronics devices and systems like light-emitting diodes (LEDs), sensors and materials. Biomimicry has led to the development of several naturally inspired structures, such as curved …

Nature provides many examples of optical structures whose properties arise from an intricate morphology. The brilliant colors seen in butterfly wings, beetle carapaces, and peacock feathers, for example, are due in large part to their complex structure, says DARPA. These hierarchical structures, scaling from micron to nanometer level, achieve remarkable …

In recent years, precision guided weapons play more and more important role in modern war. One of the greatest strengths of a precision strike missile is a reduction in the number of weapons or aircraft sorties required to destroy a target. Strategy Analytics forecasts the global Smart Weapons (SW) market …

Humans view the intensity of light as the various colors of the spectrum. Characteristics of light include amplitude (intensity), frequency (color), polarization, and coherence. The human eye has cone cells, that correspond reflected light from objects into colors which range from wavelengths of approximately 400-700nm. Polarization, the direction in which …

Sensors allow humans to feel and understand their world, and their development lays the foundation for the fulfillment of information society and has formed a huge industry. Photonic sensors are defined as sensors that sense, emit, receive and convert the light energy into electrical signals. Photonics sensors deal with the …

Sensors allow humans to feel and understand their world, and their development lays the foundation for the fulfillment of information society and has formed a huge industry. For its implementation the Internet of Things relies heavily on sensor technology.In the grand world of the “internet of things” (IoT), there are …

One of the most challenging tasks in any aerial combat situation is to determine which assets on the ground should be targeted and which ones should be avoided. This is particularly challenging in the situation where enemy assets are camouflaged or hidden amongst civilian assets. Because of this a practice …
