Using the holodiagram to explain light-in-flight recording by holography

摘要

Abstract: Light-in-flight recording by holography is originally based on the holo- diagram which is a diagram first designed to simplify the making and evaluation of holograms. It was soon found to include much more general uses than first expected. During the 20 years since its introduction, we have applied this diagram to many different fields such as holography, interferometry, diffraction, Fermat's principle, light-in-flight recordings, three-dimensional measurements with ultrashort lightpulses, and the special theory of relativity. !9
