Real-time holographic interferometry performed with two very thin, parallel, closely spaced object illumination beams can be used to produce a time-varying irradiance which, when incident on a photodetector, gives a signal whose analysis indicates both the normal displacement and tilt at a point on the object surface. The signal also contains information about in-plane translation which can be utilized in some cases.
