Wong, Albert Kai-Wai 2014-12-16T19:12:27Z 2014-12-16T19:12:27Z 10000-01-01 1981 1981 Scalar diffraction theory is used to derive the final fringe formation equations in a spatial filtering setup for a double-apertures specklegram. Both the pointwise and full-field filtering setups are analyzed. The resulting equations are shown to be more complete and exact than the equations from the conventional Moire analysis. The range of possible in-plane displacement measurement is analyzed. Several experimental demonstrations are presented. The results agree very well with the equations derived and are within the predicted range of measurement. Made available in DSpace on 2014-12-16T19:12:27Z (GMT).
