ABSTRACT:
A system is presented for the remote detection and imaging of objects at night. In accordance with the present invention, a laser is used to generate short pulses of infrared light with pulse widths on the order of nanoseconds. The laser light is expanded by optics and projected at the target scene. An intensified CCD (charge coupled device) camera is electronically shuttered after an appropriate time delay such that the image formed by the camera is composed of infrared light backscattered by the target from a range of r.
