Paper Abstract

The use of reference mirror rotation during the production of a double-exposure hologram is discussed. The rotation of the mirror introduces a phase shift across the hologram that can be observed by scanning one''s head from one end of the hologram to the other. The sign ambiguity of the fringe order can be resolved by noting the apparent motion of the fringes as one scans one''s head across the hologram. This method is easily adapted to existing setups does not distort the original fringe pattern and the amount of phase shift across the hologram can be controlled easily. Sample experiments showing quantitative and qualitative results on a circular membrane are presented. 1.
