Abstract
Most current systems for the investigation of biological motion are pointwise rather than full field techniques. The aim of this research is to achieve a full field semi-quantitative measure of motion. Systems being looked at range from linearly moving mechanical objects to movement within biological systems. The methods described can be used to detect in-plane and out-of-plane motion, and are based on the first order spatial statistics of time-integrated speckle patterns, especially speckle contrast. In addition to a photographic investigation of time integrated speckle, a digital processing technique has been developed. This computational technique is designed to produce a contrast map relating to the motion in the target field, with the advantage of working in quasi-real time. A digital method of simulating both partially and fully developed speckle patterns has also been studied.
