Holography at the U.S. Army Research Laboratory: Creating a Digital Hologram
Abstract
This report describes how to create a digital hologram. Creating a hologram is the first step in supporting the U.S. Army Research Laboratory's efforts to remotely sense high spatial resolution three-dimensional (3-D) images. The digital hologram itself is an interference pattern of two sources of light, one source being from a laser that illuminates a target object and the other source being the light from the target itself. A holographic image has several components, and these components come from the mathematics that describe holography. These different components are discussed. Finally, a comparison is made between a holographic image and regular images that might be made with a digital or film camera.
