Paper Abstract

When an object being tested and its holographic image are 'superimposed for real time holographic interferometry studies a distorted fringe field is normally observed as a result of emulsion shrinkage on the hologram plate. A liquid gate is commonly employed to eliminate emulsion shrinkage effects. This paper describes an alternative technique for reducing these effects which requires only that the plate be overexposed and underdeveloped.
