Diffraction in a volume hologram made simple

Abstract

Dedicated to Professor Partha Banerjee for his enormous contributions to the advancement of research and education in holography through his unique vision and outstanding dedication A volume hologram is different from a plane hologram owing to the non-negligible thickness along the direction of the diffracted light. The diffraction calculation from a volume hologram becomes complicated when the incident light is not a plane wave. In this paper, we introduce a calculation model, the VOHIL model, and make it simple to figure out the mechanism.
