The phase distribution is extracted from the optical fringe pattern by using S-transform gradient and S-transform phase methods. Furthermore, a Gaussian white noise is added to the fringe pattern to test the noise immunity of S-transform. The recovered phase distributions both by S-transform gradient method and phase method are compared with the simulated one.eninfo:eu-repo/semantics/closedAccessConference Object899684684N/AWOS:0002466479003982-s2.0-34547438818Q4
