Measurement of subspeckle-size changes by laser-speckle photography

Not Accessible

Your library or personal account may give you access

Abstract

A simple method for the measurement of subspeckle-size lateral changes by double-exposure laser-speckle photography is described and practically demonstrated. It requires a known lateral movement of the subject (or the camera) orthogonal to that of the unknown movement. The orientation of Young’s fringes gives the unknown deformation. The method is time ordered and reasonably sensitive. The lower measurement range can easily be reduced to 1 order of magnitude of the usual limit.
