Precision coordinate measurements using holographic recording

Holography offers unique advantages over conventional photography or traditional photogrammetric techniques in the recording of three-dimensional objects over a large depth of field. However, there are several fundamental problems in recording and replay that must be understood and overcome. The authors discuss the techniques of in-line and off-axis holography, and the problems that are encountered in practice. They present a review of several applications in particulate recording, bubble chamber holography, fuel-rod 'hologrammetry', endoscopy etc. The emphasis is on precision three-dimensional coordinate measurements from holographic images.
