Heisenberg principle applied to fringe analysis

Optical techniques that are used to measure displacements utilize a carrier. When a load is applied the displacement field modulates the carrier. The accuracy of the information that can be recovered from the modulated carrier is limited by a number of factors. In this paper these factors are analyzed and conclusions concerning the limitations in information recovery are illustrated with examples taken from experimental data.
