Holographic detection of surface topography by depth contouring

The interferometric holographic technique in real time here described is based on the use of one wavelength for recording and another for reconstructing the hologram: the interference between the image of the surface and its holographic image produces interference fringes that are contour levels.

Summary:The interferometric holographic technique in real time here described is based on the use of one wavelength for recording and another for reconstructing the hologram: the interference between the image of the surface and its holographic image produces interference fringes that are contour levels. The technique has been applied to a prismatic face of a quartz crystal.
