Abstract: The optical sensor (10) has a multiple telescope assembly (12), a rotating periscope assembly (14), an imager optical system (16) and a detector (18). The sensor (10) may be utilized with visible, ultraviolet or infrared wavelength radiation. Each telescope (12) views a particular sector of a scene. The rotating periscope (14) multiplexes the output of each telescope (12) to provide a combined wide field of view of each of the sectors. The system may be used in various types of navigation, pilotage, and monitoring systems.

Abstract: An integrated multi-spectral target generator for use with electro-optical systems that comprise visible and infrared sensors and a laser designator. A pinhole is illuminated with a multiband source to produce a single visible and infrared target which is detected by visible and infrared sensors. A pair of beamsplitters and an associated corner reflector precisely define the parallelism of the visible and infrared radiation transmitted from the multiband source along an optical axis. A reflective telescope is used to project the visible radiation to the visible sensor and the infrared radiation, in conjunction with a periscope, to the infrared sensor. The target generator does not require precision stabilization and uses a single inherently parallel path to generate visible and infrared boresight targets. The target generator enables a boresight procedure to be completed in about ten seconds without firing the laser designator.
