Abstract: A reusable interdiction apparatus that makes use of a housing of dimensions making the housing suitable to be carried and thrown by an individual. A light source is disposed within the housing and adapted to project an optical signal through a portion of the housing. A controller is used for controlling operation of the light source. A power source is disposed within the housing and used for powering the controller and the light source.

Abstract: A system and methods for broad area visual obscuration around a platform. In one embodiment the system comprises a source of visible light, shaping optics and projecting optics. The system projects a light beam onto an illumination area in a sweeping pattern to repetitively illuminate all portions of the illumination area, such that a stationary observer within the illumination area receives repeating pulses of the light at a power, intensity, frequency and duration sufficient to visually impair the observer so as to substantially prevent the observer from discerning the platform between pulses. The light pulses are capable of temporarily blinding human eyes but incapable of causing permanent vision loss.

Abstract: Methods and systems for detection of. One method includes receiving light of a predetermined wavelength range from a source, and splitting the received light into multiple components having differing wavelengths. The method further includes directing the components toward individual locations spaced from one another. In addition, this illustrative method includes detecting at least some of the components at the locations. One illustrative system includes a plurality of detectors provided along an image facing plane of an array, wherein each detector has a width less than or equal to that of its conesponding pixel location, wherein at least two detectors are located within a single pixel location, wherein the size of each pixel location is approximately equal to the blur spot or smallest visible spot for the focal plane array, and a plurality of light pipe regions, wherein at least two light pipe regions are located within a single pixel location.

Abstract: An apparatus for selectively limiting undesired radiation from a scene which, in one embodiment, includes an optic that is operative to attenuate radiation by selectively losing transparency in response to radiation within a first wavelength band from a source. The loss of transparency affects the passage through the optic of radiation within a second wavelength band from that source. The optic can be positioned between a sensor and the scene such that the sensor is configured to receive radiation from the scene through the optic. In one embodiment, an optical limiter includes a plurality of such optics, wherein the optical limiter is configured to facilitate transmission of light corresponding to a scene, and wherein each optic is configured to receive a respective portion of the light corresponding to a respective portion of the scene. A light detector assembly and a method of limiting light energy are also included.
