Abstract
A shared-aperture EO imaging and ranging sensor is implemented by time multiplexing an optical imaging channel and an optical ranging channel. The optical ranging channel is allocated the “unused portion” of each frame; that portion of the frame that is reserved from electronics processing of the imaging channel. The electronics processing of ranging channel is performed during the integration period of the next frame. This allows ranging to be provided without sacrificing the performance of the imaging channel. Ranging may be provided using either “coded aperture” or “wavefront coding”.
