Abstract

The fringe visibility in pulsed subtraction and addition TV holography is described and compared. Correlation fringe patterns, obtained by conventional double-pulse addition TV holography, are characterized by their relatively poor quality. The fringe visibility is significantly improved by applying subtraction in combination with the double-pulse technique. This is achieved by using a standard interline transfer CCD camera. Double-pulse subtraction TV holography is especially useful for subfringe measurements, and vibration amplitudes of less than λ/50 have been detected on raw double-pulse subtraction interferograms.
