Abstract

We have developed a whole set of range gated laser imaging system with ~3km maximum acquisition distance, the system uses a Nd:YAG electro-optical Q-switched 532nm laser as transmitter, a double micro channel plate as gated sensor, all the components are controlled by the a trigger control unit with accuracy of subnanosecond. A imaging scheme is designed for imaging the large building ~500m away, and a sequence of images are obtained in the experiment, which are the basic data for 3D reconstruction; to improve the range resolution, we study the temporal distribution of intensity of the received signal, and use centroid algorithm for data processing. We compare the 3D image with the theoretical model, and the results are corresponding.
