基于偏振的收发一体化亚纳秒脉冲激光探测系统
摘要：
本发明涉及一种基于偏振的收发一体化亚纳秒脉冲激光探测系统，属于激光技术领域。本发明是由偏振激光作为探测光源，通过旋转同轴的1/2波片和1/4波片调整线偏振激光的偏振方向，实现发射信号与接收信号在偏振分光棱镜处分离。传统的光学发射、光学接收窗口分离的激光探测系统存在探测盲区，而本发明采用了光学系统收发合一的模式，并采用亚纳秒脉冲激光进行探测，提高了探测过程中的抗悬浮粒子和云雾干扰能力，同时提高了探测精度。尤其适用于中近程激光测距，具有良好的应用前景。
摘要（英）：

The invention relates to a receiving and transmitting integrated sub-nanosecond pulse laser detection system based on polarization, and belongs to the technical field of laser. The receiving and transmitting integrated sub-nanosecond pulse laser detection system uses a polarized laser as a detection light source, and the polarization direction of linear polarized laser is adjusted by rotating coaxial 1/2 wave plate and 1/4 wave plate to realize the separation of a transmitted signal from a received signal at a polarization beam splitter prism. The conventional laser detection system with separated optical transmitting and optical receiving windows has detection blind areas, but the receiving and transmitting integrated sub-nanosecond pulse laser detection system adopts an optical system receiving and transmitting integrated mode, and sub-nanosecond pulse laser is adopted for detection, the suspended particle resistance and cloud interference resistance during detection are improved, and the detection accuracy is also improved. The receiving and transmitting integrated sub-nanosecond pulse laser detection system is particularly suitable for medium-short-range laser ranging, and has a good application prospect.
