摘　　要：利用激光雷达双光束扫描接收方法可以在激光发射频率与振镜扫描频率一定时 ,使扫描像元素加倍 ;在像元素不变的条件下 ,使扫描帧频加倍 ;并具有增加最大非模糊距离等优点 ,降低了对扫描与激光器的要求。具有应用于高帧频。The method of scanning and receiving with two beams can double the scanning image's pixels without increasing the laser's pulse repetition rate and the scanner's operating frequency, or double the frame frequency while the pixels remain the same. It can also increase the maximum of non-fuzzy distance and depress the requirement for the scanner and the laser. It is in prospect of being applied to laser radar with high frame frequency or high pixels.
