    Abstract: An interrogator (44) identifies an interrogated object (60) using a light transceiver (42) and a dynamic optical tag (70) associated with the interrogated object (60). The dynamic optical tag (70) receives an output light beam (48) from the light transceiver (42) and controllably reflects the light beam back to the light transceiver (42) as an input light beam (52). The dynamic optical tag (70) includes a controllable light reflector (72) that is controllable between a reflective state and a non-reflective state and having a modulation signal input (74), and a controller (76) that provides the modulation signal input (74) to the controllable light reflector (72). In operation, the interrogator (44) transmits an interrogation light beam from the light transceiver (42) to the dynamic optical tag (70), the dynamic optical tag (70) reflects a modulated interrogation light beam back to the light transceiver (42) as the input light beam (52), and the light transceiver (42) receives and analyzes the input light beam (52) to determine an identity of the dynamic optical tag (70) and the interrogated object (60). A field-of-regard broadening structure such as a volume hologram (88) preferably overlies the controllable light reflector (72).

    Abstract: An imaging polarimeter sensor (20) includes an achromatic beamsplitting polarizer (30) that receives a polychromatic image beam (22) of a scene (24) and simultaneously produces a first polarized polychromatic image beam (32) and a second polarized polychromatic image beam (34). The second polarized polychromatic image beam (34) is of a different polarization than the first polarized polychromatic image beam (32) and is angularly separated from the first polarized polychromatic image beam (32). The achromatic beamsplitting polarizer (30) preferably includes a Wollaston prism (50) through which the polychromatic image beam (22) passes, and at least one grating (54, 56) through which the polychromatic image beam (22) passes either before or after it passes through the Wollaston prism (50). An imaging detector (38) receives the first polarized polychromatic image beam (32) and the second polarized polychromatic image beam (34) and produces an output image signal (40) responsive to the first polarized polychromatic image beam (32) and the second polarized polychromatic image beam (34).
