Optical receiving solution for optical scanning lag effect of LADAR
Optical scanning plays a very important role in LADAR system for large field of view (FOV). But it introduces the optical scanning lag effect due to the optical scanning and the time delay between laser pulse transmitting and receiving. Optical scanning lag angle will make 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 firstly computational analyzed in detail in this paper. A novel optical receiving design approach is proposed, and the experimental result is given.
