摘要

This study presents Single-Shot Polarization-Coherent Modulation Imaging (SSPCMI), an innovative technique that achieves simultaneous reconstruction of amplitude, phase, and birefringence properties from single-shot diffraction patterns. The method employs a phase modulation plate synchronized with a polarization camera to modulate four orthogonal polarization states, enabling iterative computation of sample characteristics. Experimental validation using CO₂ and nanosecond pulse laser-induced damage in fused silica substrates demonstrates distinct interaction mechanisms between the laser types and the material matrix, with a calibrated spatial resolution of 156.25 μm line width. The proposed technique establishes a high-efficiency, polarization-sensitive imaging framework for comprehensive material characterization.
