摘要
基于相干探测的单像素激光成像雷达是一种结合光场的主动调制和光学相干探测、通过无空间分辨能力的单像元探测器便可以获取目标信息的计算成像技术,在高维信息获取和抗背景光干扰方面具有显著优势。本文简述了近年来发展起来的两种新型相干探测单像素激光成像雷达(合成孔径激光成像雷达和激光关联成像雷达)的基本原理和特点,介绍了近期取得的主要研究进展,并对其未来发展趋势进行了展望。
Single pixel imaging lidar via coherent detection is a computational imaging method that obtains the target's information through a detector without the ability of spatial resolution,by combining active modulation of light field with optical coherent detection.This method has significant advantages in high-dimensional information acquisition and anti-background light disturbance.The basic principles and characteristics of two new single pixel imaging lidar via coherent detection such as synthetic aperture imaging lidar and ghost imaging lidar,are briefly reviewed and their main research progress are introduced in recent years.The future development trend is also prospected.
