摘要： A sensor system senses a scene and includes a dual-band imaging infrared detector lying on a beam path, wherein the infrared detector detects infrared images in a first infrared wavelength band and in a second infrared wavelength band; and a two-color cold-shield filter lying on the beam path between the infrared detector and the scene. The cold-shield filter defines a first aperture size for infrared light of the first infrared wavelength band, and a second aperture size larger than the first aperture size for infrared light of the second infrared wavelength band. The first infrared wavelength band has wavelengths less than wavelengths of the second infrared wavelength band.

The sensor system includes an imaging sensor operable to image light of the two different spectral bands, a common optics having at least one reflective or refractive optical element, and a wavelength-selective beamsplitter on the light path between the target and the imaging sensor. The wavelength-selective beamsplitter splits the light beam into two subbeams, one subbeam for each of the two different spectral bands, that are respectively incident upon two different locations of the imaging sensor. The imaging sensor may be used to detect buried explosive mines.

摘要： An imaging polarimeter sensor includes an achromatic beam-splitting polarizer that receives a polychromatic image beam of a scene and simultaneously produces a first polarized polychromatic image beam and a second polarized polychromatic image beam. The second polarized polychromatic image beam is of a different polarization than the first polarized polychromatic image beam and is angularly separated from the first polarized polychromatic image beam. The achromatic beam-splitting polarizer preferably includes a Wollaston prism through which the polychromatic image beam passes, and at least one grating through which the polychromatic image beam passes either before or after it passes through the Wollaston prism. An imaging detector receives the first polarized polychromatic image beam and the second polarized polychromatic image beam and produces an output image signal responsive to the first polarized polychromatic image beam and the second polarized polychromatic image beam.

摘要： An imaging optical system includes a subtelescope array, with at least two subtelescopes, each having a single entrance pupil and an exit light beam. Each subtelescope has an optical pointing axis, and the pointing axes for the subtelescopes are parallel. An imager forms an image from the exit light beams at an image surface, where there is a sensor such as a focal plane array. Preferably, a phase shifter array includes a phase shifter for each of the subtelescopes. The phase shifter array receives the exit light beam of each of the subtelescopes and has a capability to adjust the phase of at least one of the exit light beams. The imager receives the phase-shifted exit light beams.

摘要： An interrogator identifies an interrogated object using a light transceiver and a dynamic optical tag associated with the interrogated object. The dynamic optical tag receives an output light beam from the light transceiver and controllably reflects the light beam back to the light transceiver as an input light beam. The dynamic optical tag includes a controllable light reflector that is controllable between a reflective state and a non-reflective state and having a modulation signal input, and a controller that provides the modulation signal input to the controllable light reflector. In operation, the interrogator transmits an interrogation light beam from the light transceiver to the dynamic optical tag, the dynamic optical tag reflects a modulated interrogation light beam back to the light transceiver as the input light beam, and the light transceiver receives and analyzes the input light beam to determine an identity of the dynamic optical tag and the interrogated object. A field-of-regard broadening structure such as a volume hologram preferably overlies the controllable light reflector.
