Hologram repositioning by an interferometric technique

Appl Opt. 1979 Nov 15;18(22):3838-40. doi: 10.1364/AO.18.003838.

Abstract

An interferometric technique for hologram repositioning is described where the hologram is compared with the interference pattern of the reference and object waves. Analytical expressions to evaluate the accuracy of the repositioning are presented for the method. Two applications of the method in metrology for micromovement measurements are proposed.
