Abstract
The laser imaging radar based on Geiger APD array detection has the advantages of high sensitivity, high frame frequency, wide field, solid, small volume, and has become the development trend of laser imaging radar. At present, the APD array has fewer pixels and fewer device arrays, which can not meet the requirements of high resolution laser imaging. In order to solve this problem, one-to-one correspondence between laser dot array and APD array pixels was proposed. The imaging resolution was improved by splicing technique, and the laser imaging field was improved by micro scanning technique. By building an experimental system, the outdoor experiment was finished which had good imaging effects. The existing APD detector(3232) was used to improve the system spatial resolution by four times(6464), and the ability of laser 3D imaging was also improved.
