Demonstration of a 532 nm Direct Detection Imaging Laser Radar Using a Digicon Receiver

Abstract

A 532 nm direct-detection imaging laser radar using a prototype Digicon receiver was constructed and has demonstrated rapid multiple retargeting over a wide field of regard obtaining single-shot images with both intensity data and three-dimensional position data for each target. Such laser radar capability is important for discrimination and targeting. The Digicon receiver system obtains 8 x 8 - pixel images of multiple targets at a rate of 15 Hz. Each image provides both intensity and range-to-target at each pixel. Results of experiments involving seven targets located at various distances along a 60 m light tunnel are presented. Future directions discussed include acquisition and hand-off, tracking, long-range experiments (- 1 km), and a 16 x 16 array Digicon tube with magnification....
