Prof. Liu Bo, Research Fellow, Institute of Optoelectronic Technology, Chinese Academy of Sciences, made new progress in the research of 3D array imaging LIDAR: the 3D imaging method based on dual polarization modulation technology and adaptive distance gating was first proposed, and the related research results were published in the near future IEEE Photonics Technology Letters (28, 3, 295-298, 2016) and Applied Optics (55, 3, A184-A190, 2016) and have applied for a patent for invention. The research system uses the high-sensitivity electron multiplying charge-coupled device (EMCCD) as the area array detector and utilizes the dual-channel high-speed electrooptic polarization modulation technology combined with the adaptive distance gating to realize the three-dimensional imaging and breaks through the traditional scanning imaging lidar unable to detect the long distance The limitations of dynamic target imaging also overcome the disadvantage of low resolution imaging with APD array detectors. In addition, the polarization beam splitter technique splits the echo beam into two at the same time, so that only one shot of laser pulse can be performed to obtain the reconstruction of the distance and obtain a three-dimensional image with the capability of "flashing" three-dimensional imaging. It can meet the needs of morphological identification and three-dimensional morphological analysis of highly dynamic targets in space, and has great potential research value and broad application prospects. The image shows the railings at the top of the tower 1 km away. (A) Gray-scale images taken with a normal daytime camera. (B) The distance images detected for an LADAR system. From the distance map can clearly see the three-dimensional structure of the railings and their spacing distance information. The above work has been the Chinese Academy of Sciences, "Hundred Talents" research funding support.
