In this paper, a fiber coupling method is presented to analyze the fiber‐optic velocity interferometric system for any reflector (optic VISAR), and the system has been developed. Optic VISAR is applied to measure the velocity profile of a diffusely reflecting surface; the experimental results fit the theory analyses fairly well. The oscillation on the velocity profile clearly shows a dispersion effect, which is the first to be obtained for such a low shocking measurement by VISAR. ©1999 John Wiley & Sons, Inc.
