I propose a holography technique that detects both three-dimensional (3D) and polarization information on incoherent light without any polarization filters. Two polarization-sensitive phase-only spatial light modulators are used to generate self-interference holograms with different polarization directions. 3D images for different polarization directions are retrieved from the recorded polarization-multiplexed holograms, exploiting the developed phase-shifting interferometry and numerical refocusing. Moreover, light-use efficiency is improved in general incoherent holography because there is no polarization filter. Its validity is experimentally demonstrated.
我提出了一种全息技术，该技术无需任何偏振滤波器就能检测非相干光的三维（3D）和偏振信息。使用两个仅对相位敏感的偏振空间光调制器来生成具有不同偏振方向的自干涉全息图。利用所开发的相移干涉测量法和数值重聚焦技术，从记录的偏振复用全息图中检索出不同偏振方向的3D图像。此外，由于不存在偏振滤波器，在一般的非相干全息术中光利用效率得到了提高。通过实验证明了其有效性。
