In this paper, a general phase retrieval method is proposed, which is based on one single interferogram with a small amount of fringes (either tilt or power). Zernike polynomials are used to characterize the phase to be measured; the phase distributi

We present an absolute calibration method for Fizeau interferometer with global optimized shift-rotation, which requires rotational and translational measurements. With a data matching method to decrease the alignment error of rotations and translati

Absolute interferometric testing method of shift-rotation in a Fizeau interferometer is effective in optical surface metrology with high accuracy and has been developed for decades. A pixel-level spatial frequency solution of interferometric shift-ro
