Paper Abstract

This paper presents an efficient method for obtaining phase distribution of an object spectrum by using a fringe scanning phase conjugate interferometer. Detailed analysis of this proposed technique is provided and experimental demonstrations for verifying this technique are also given. The major advantages of this proposed technique are its potential high accuracy of the phase measurement and low space-bandwidth product requirement for the detection system.
