激光遥感是一种强大的工具，可以精确测量运动目标的速度。至关重要的是，大多数传感技术是二维的，只能直接确定沿着视线的速度。在此，我们提出了一种新的三维技术，可以同时直接测量合作目标的纵向和角速度。该技术是基于使用复矢量光束，其偏振和空间自由度以不可分离的方式耦合。我们通过一个原理验证实验来证明我们的技术。(C) 2019美国光学学会
Laser remote sensing represents a powerful tool that enables the accurate measurement of the speed of moving targets. Crucially, most sensing techniques are two-dimensional (2D) and only enable direct determination of the speed along the line of sight. Here we put forward a novel three-dimensional technique that enables the direct and simultaneous measurement of both the longitudinal and angular speed of cooperative targets. This technique is based on the use of complex vector light beams, whose polarization and spatial degree of freedom are coupled in a non-separable way. We present evidence of our technique by performing a proof-of- principle experiment. (C) 2019 Optical Society of America
