Charge-Coupled Device Image Acquisition For Digital Phase Measurement Interferometry
Abstract
Direct phase measurement interferometry can provide a fast and accurate means of obtaining surface data. Solid-state detector arrays are ideal imaging devices for these instruments. These imagers can be coupled to micro-computers for phase calculation. This article discusses the use of CCD arrays and techniques for digitizing and interfacing these arrays to microcomputers.
