Abstract

A new ladar design and implement with a small size and real-time imaging using a MEMS microscanning mirror are described in this paper. The new ladar system consists of laser diode, collimating lens, beam splitter, MEMS microscanner, bandpass filter, photodetector and signal processing devices. The system structure and its parameters are discussed in detail. A range resolution of about 1 cm, FOV of 30° and resonant frequency of 1.5 KHz can be achieved. This next generation of three dimensional MEMS ladar system will be high accurate, low price, small size and real-time imaging.
