Single pulse light-in-flight recording by holography

Abstract

We have succeeded we believe for the first time, in making a light-in-flight (LIF) recording using one single pulse of a mode-locked frequency doubled Nd:YAG laser. Many experiments made earlier with multiple picosecond pulses have been repeated and the results were the same. New experiments have become possible such as the contouring of a fast moving object and recording through a nonrigid scattering medium. We demonstrate a LIF transmission method for rejecting scattered light which can be developed into a method for diagnostic imaging inside living tissue.
