Paper Abstract

In the present paper holo-interferometric fringe patterns are recorded within a cavity using two opposing collinear panoramic annular lenses. One panoramic annular lens is used to illuminate the cavity wall with coherent light and the resulting intensity distribution is holographically recorded through the second panoramic annular lens. Interference fringes are obtained in real time by comparing holograms recorded before and after the cavity shape is modified. Future plans are discussed for practical implementation of the method including the use of digital image processing with a minicomputer for automatically accessing and analyzing the fringe patterns recorded through the system and the incorporation of fiber optic components for making holographic measurements within the cavity using a compact rugged probe. 1.
