【Abstract】 Phase object ia inserted into one of the two beams of the Mach-Zehnder interferometer. With the two beams interfering1, nonlinear holograms are obtained. Using the high degree diffracted waves twice, we have obtained lower noise phase difference amplification of over 100 times. The theoretical results coincides with the experimental ones.更多还原
