ABSTRACT:
A non-scanning heterodyne optical imaging sensor which utilizes a multi-frequency coherent light source to provide a plurality of points of different frequencies on a single detector on which the image of an object is also projected. Each point acts as a local oscillator which is sensed/filtered to construct the image of the object without mechanical scanning.
