Paper Abstract
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 automatic image processing methods to calculate the three dimensional surface deformation.
