摘　　要：为了研究并行相移同轴数字全息系统中偏振态传输的问题,提出考虑偏振的并行相移同轴数字全息系统的修正模型,并依据此模型提出偏振成像方法。首先,介绍了理想情况下并行相移同轴数字全息的原理,然后,介绍了考虑偏振的并行相移同轴数字全息修正模型,最后,基于此模型提出了实现偏振成像的方法。实验结果验证了模型的可行性,通过这种方法可以得到外表信息,成像分辨率可达到14μm。该方法扩充了数字全息系统的功能,通过该系统可以对物体的偏振态进行成像。In order to study the issue of polarization state transmission in parallel phase-shifting coaxial digital holographie system,a modified model of parallel phase shifting coaxial digital holographie system considering polarization is proposed,and a polarization imaging method is proposed based on this model.Firstly,the principle of parallel phase shifting coaxial digital holography under ideal conditions is introduced.Then,the modified model of parallel phase-shifting coaxial digital holography considering polarization is introduced.Finally,based on this model,a polarization imaging method is proposed.The experimental results verify the reliability of the model.The appearance information can be obtained by using this method,and the imaging resolution can reach 14μm.This method expands the functions of digital holographic system.Through this system,the polarization state of the object can be imaged.
