提出一种实现偏振差分干涉成像的新方法。该方法利用微透镜阵列和渥拉斯顿棱镜,实现一次成像就能获取目标的平行和垂直偏振分量的光谱图像,且具有无机械运动部件和共光路的优点。通过理论分析和模拟仿真,获取复色光以及632.8 nm的单色光的正交偏振分量的光谱图像。仿真分析表明,该方法能够有效地同时获得目标的差分偏振光谱图,有利于实现实时探测目标的偏振光谱信息。

A new method that can realize polarization-difference interference imaging was put forward. By employing microlens arrays and Wollaston prism, this method can simultaneously acquire the spectral images of orthogonal polarization components of targets, and has the advantages of no mechanical movable devices and optical path coaxial. The spectral images of orthogonal polarization components of polychromatic light and monochromatic light with 632.8 nm were acquired with theoretical analysis and simulation. The simulation analysis show that this method can effectively and simultaneously obtain the polarization difference spectral images of the incident light, and is useful for realizing the detection of the polarization spectrum in real time.
