| Abstract: | This paper discussed the study of the principle and experiments of holographic real-time three-slit interferometer with its lateral slit tuned. The calculation equation of the changes in distribustion of real time three-slit diffracted light intensity as lateral slit phase changed was derived.The measurement of phase changes of lateral slit were made based on the principle and characteristics of three-slit diffraction and by reconstructing holographic real-time three-slit diffracted light waves.The experimental methods can be applied to the measurement of unevenness of optical surface. |
