Paper Abstract

Optical scanning plays a very important role in LADAR system for large field of view (FOV). But it introduces a Optical scanning lag angle which depends on the detecting range and the angular rate of scanner. Optical scanning lag angle makes a part of received optical energy fall out of the optical sensitive area of detector which will greatly degrade the detecting performance of LADAR in many cases. Optical scanning lag effect and optical scanning lag angle are computational analyzed in detail in this paper. And two conceptual solutions, sub-area receiving way on unit optical sensitive area and electrical scan receiving way on detector array, are proposed.
