Double-frequency grating shearing interferometer with built-in phase-shifting function for robust multi-level phase retrieval
In this paper, we propose and demonstrate a novel interferometer and signal process to retrieve two-dimensional signals with multilevel phases. The interferometer is based on a shearing interferometry with double-frequency grating, and phase-shifting interferometry is derived as a built-in function...
