Zusammenfassung:	A device and method for accurately sensing the direction and magnitude of small displacements between two objects, independent of the distance between the objects, utilizing a monochromatic light source and a reflector to produce a light standing wave pattern and a transparent photosensitive detector to detect the number of crests and/or nodes of the light standing wave pattern intercepted.
