NON-MECHANICAL STEP SCANNER SYSTEM FOR ELECTRO-OPTICAL SENSORS

摘要

A non-mechanically scanned optical sensor system includes a stationary sensor array (24) having an image plane, a lens system (14) characterized by a field of view corresponding to an image of a scene viewed by the lens system (14), an image divider for dividing the image into plural contiguous sub-images, and a device for directing each of the sub-images onto substantially the entirety of the image plane of the sensor array (24). The image divider is a spatial light modulator (28) having an array of optical shutters (30) controlling respective sub-images. The directing device is an array (32) of small lenses (34) co-extensive with respective light beams of respective sub-images of an image viewed by the lens system (14).
