A full-Stokes polarization imaging method based on the self-organized grating array was presented. By focusing the ultra-fast laser with moderate fluence into fused silica, the self-organized grating array was fabricated, featuring the optical properties similar to wave plates. A set of four independent polarization measurements were simultaneously acquired with designed grating array mounted in the focal plane of an imaging detector. Experimental results including the device fabrication, calibration and optimization were presented. Finally, a principle verification experiment was implemented for our polarization imaging method.
提出了一种基于自组织光栅阵列的全斯托克斯偏振成像方法。通过将适度强度的超短激光聚焦到熔融石英中，制备出自组织光栅阵列，其光学性能类似于波片。通过将设计的光栅阵列安装在成像探测器的焦平面上，可以同时获得四组独立的偏振测量结果。实验结果包括器件制备、校准和优化。最后，对我们的偏振成像方法进行了原理验证实验。
