Abstract: A system and method for enhanced conditioning light so a camera can capture images from it in a variety of brightness ranges is presented. A camera has an optical lens and a photochromic filter. The photochromic filter may be placed in front of the lens. The photochromic filter extends an exposure range of the camera without the need for a mechanical iris.

Abstract: A mid-wave infrared system provides high spatial and temporal resolution measurements of atmospheric temperatures and moisture fields using a constellation of low earth orbit satellites. The disclosed system is smaller, lighter, less complex, and requires less energy than existing systems, due to implementation of an infrared avalanche photodiode array detector that provides enhanced sensitivity with reduced cooling requirements, and an Offner spectrometer having a novel a refractive element inserted near the grating that reduces the size and power requirements of the spectrometer. Embodiments of the disclosed method include deploying a constellation of devices for cooperative infrared sensing of atmospheric phenomena at similar rates, lower cost, and much higher resolution compared to geosynchronous approaches. Some embodiments further include combined analysis of measurements obtained by the disclosed devices with complementary measurements made by other low-earth and high-earth orbital and/or ground-based devices.

Abstract: A surveillance sensor system is described. The surveillance sensor system includes a polygonal-shaped assembly having four substantially identical quadrant segments. Each of the quadrant segments includes a first set of lens, a second set of lens, and a third set of lens. Images captured by the first, second and third sets of lens can be combined to form a telecentric image on an intermediate image plane. The surveillance sensor system also includes a relay optic module having a set of lens, multiple focal plane array detectors and a dewar. The relay optic module can re-image the telecentric image located on the intermediate image plane onto an image plane.
