摘要
以极高频率的伪随机调制连续毫瓦级的半导体激光,配以现代微机系统控制的高速硬件累加平均及相关器所构成的小型便携激光雷达系统,用于低空大气污染的监测,不仅可达到较高的探测率,而且可获得数十米的空间分辨率。本系统的最大实用性还在于小型便携,操作简单。
This lidar system is a small--scale construction applied to measurement of pollut-ants. It makes use of a small--power continuous--wave laser diode as its light source.The pseudo--random--modulation CW technique is adopted in this lidar. To improvethe signal-to--noise ratio(SNR), the signal--accmulation--average technique is used.This lidar construction is compact, portable, and operable by one person. It may beapplied to the measurement of aerosols and particulates.
