Data processing method of imaging velocity interferometer system for any reflector

The data processing procedure for imaging Velocity Interferometer System for Any Reflector(VISAR) has been listed with Fourier transform method. Fringe loss problem in shock wave experiment with imaging VISAR technique has been researched. The fringe loss image from the reference has been processed with Fourier transform method. The fringe image should be clear and uniform, and the one-dimensional Fourier transform method is recommended to reduce the difficulty in filtering the image. The method to confirm the loss point in the fringe loss has been provided. The difference between interference fringes for the opaque and transparent targets is discussed. It is concluded that the fringe from the transparent target should be preprocessed with extension technique before using the normal data
