Abstract

We propose parallel phase-shifting radial shearing interferometry and apply this technique to single-shot wavefront measurement. This technique records a single interference image consisting of the combination of radially sheared two object waves. By applying parallel phase-shifting interferometry and a wavefront reconstruction algorithm to the recorded single interference image, the phase image of the measuring object wave is obtained. We numerically simulated single-shot wavefront measurement by using the proposed technique. It was assumed that the object was two particles. The amplitude and phase images of the particles were assumed as Gaussian distribution. The cross-correlation coefficient between the original phase image and the phase image reconstructed by using the proposed technique was 0.984.
