Data Processing of Dynamic Calibration of Linear Shear Spatial Modulation Snapshot Imaging Polarimeter
The linear shear spatial modulation snapshot imaging polarimetry technique based on dynamic calibration can provide more accurate real-time measurements of target's polarization information under dynamic environments (such as temperature changes). However ,experimental noise causes strip distortions in the inverted image. To address this issue ,the principle of dynamic calibration technology and the quantitative solution process of target's phase were systematically analyzed. A noise recognition and phase correction method was proposed ,which combined phase difference and bi-linear interpolation. Experimental and calculation results show that after phase calculation and correction ,the strip distortions are removed and the quality of inversion imaging is improved. This provides support for the real-time application of the spatial modulation snapshot imaging polarimetry technique in high phase change and low signal-to-noise ratio environments ,and promotes its practical application in engineering under dynamic environments.
