An Automated Holographic Interferometry Data Reduction System

Abstract

Probably the most severe obstacle in the widespread use of holographic interferometry has been the methodology for extracting the data from the hologram in a timely fashion. Holography makes possible the recording of more data than can normally be used because of this limitation. In recent years great strides have been made toward solving the problem of automated data reduction. Available co puter power, new codes, and detector arrays have played key roles. This paper reports the development and application of a low cost, automated interferogram analysis system including both hardware and software.
