英文摘要: To improve the resolution in 3D range-gated imaging, an adaptive polarization-modulated method using electron multiplying charge-coupled devices (EMCCDs) is proposed in this letter. With polarization beam splitting, the returned light is separated into two orthogonal polarized components, which are modulated by cos(2) function and sin(2) function, respectively. Based on a dual EMCCDs structure, both a depth map and an intensity image can be reconstructed from the two modulated images instantaneously, which will enhance the performance of dynamic imaging. The results show that the range accuracy of the interested objects in the scene can be promoted from 4.4 to 0.26 m with the art of adaptive gate-opening range.
