| Abstract | A novel technique for holographic phase shifting interferometry is described, in which the hologram is written on a liquid crystal television. Phase shifting is achieved using binary gratings, combined with the hologram on the liquid crystal panel. We describe a system which was used to measure small out-of-plane displacements of rough surfaces, and demonstrate its operation with experimental results. |
