An innovative flash LIDAR (light detection and ranging) system with high spatial resolution and high range precision is proposed in this paper. The proposed system consists of a polarization modulating Pockels cell (PMPC) and a micro-polarizer CCD camera (MCCD). The Pockels cell changes its polarization state with respect to time after a laser pulse is emitted from the system. The polarization state of the laser-return pulse depends on the arrival time. The MCCD measures the intensity of the returning laser pulse to calculate the polarization state, which gives the range. A spatial resolution and range precision of 0.12 mrad and 5.2 mm at 16 m were obtained, respectively, in this experiment.
本文提出了一种具有高空间分辨率和高距离精度的创新型闪光激光雷达（光探测和测距）系统。所提出的系统由一个偏振调制普克尔盒（PMPC）和一个微偏振器电荷耦合器件相机（MCCD）组成。从系统发射激光脉冲后，普克尔盒的偏振态随时间变化。激光回波脉冲的偏振态取决于到达时间。MCCD测量返回激光脉冲的强度以计算偏振态，从而得出距离。在该实验中，在16米处分别获得了0.12毫弧度的空间分辨率和5.2毫米的距离精度。
