Photonic ADCs have removed the bottlenecks of bandwidth limitations and timing jitter of electronic analog-to-digital converter (ADC)

The performance of digital receivers used in modern military radar, communication, and surveillance systems is often limited by the performance of the analog-to-digital converter (ADC) used to digitize the received signal. Ultrafast ADCs are critical in military applications such as military software-defined radio, radar, and electronic counter-warfare (ECW) that require …

Bio-Inspired or Biomimetic Photonics create highly selective Gas sensors and Artificial Eye like insects

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 …

DARPA’s thrust on Bio-Inspired Photonics

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 …

Next generation precision strike missiles carry Intelligent Missile IIR Seekers for High hit probability against stationary and moving targets

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 …

Polarization-based imaging systems or cameras enhance machine vision, autonomous vehicle navigation, facial recognition, and military target detection

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 …
