Document Type and Number:
Japanese Patent JPH09504379
Kind Code:
A
Abstract:
A non-mechanically scanned optical sensor system which includes a stationary sensor array having an image plane, a lens system characterised by a field of view corresponding to an image of a scene viewed by the lens system, 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. The directing device in one embodiment is an array of small lenses co-extensive with respective light beams of respective sub-images of an image viewed by the lens system. In another embodiment, both the image divider and the directing device are realised together as an X-Y addressable array of electrically deformable optical elements, such as silicon micro-mirrors, individually directing respective ones of the sub-images to the sensor array. In another embodiment, the image divider is a spatial light modulator having an array of optical shutters controlling respective sub-images.
