ANALYSIS OF HOLOGRAPHIC FRINGE DATA USING THE DUAL REFERENCE APPROACH
UNSPECIFIED. (1991) ANALYSIS OF HOLOGRAPHIC FRINGE DATA USING THE DUAL REFERENCE APPROACH. OPTICAL ENGINEERING, 30 (4). pp. 452-460. ISSN 0091-3286Full text not available from this repository.
A new method for extracting quantitative information from a double exposure holographic interferogram is presented. Dual reference beams are used to produce continuously variable phase differences between the two images of the object at the recording stage of the hologram. Image reconstruction at three known phase differences, via a CCD camera and digital framestore, allow new automatic image processing methods to calculate the three-dimensional surface deformation.
