A simple and rugged optical hardware configuration for digital holography of microscopic reflecting structures is presented. The proposed technique employs a cube beam splitter, oriented as in the Gates interferometer, for recording a hologram. The experimental results for the United States Air Force resolution target and the reflection coating of a compact disk are presented. The salient features of the proposed configuration for reflection digital holography are its simplicity and low sensitivity to ambient vibrations.
