Abstract: A displacement sensor measures displacement or distance in a plurality of orthogonal directions. In one embodiment, the present invention comprises an apparatus for determining a distance to an object. The apparatus includes a sensor housing, an optical source, an optical detector, and a means for selectively redirecting incident and reflected light. In particular, the optical source is affixed to the sensor housing and generates an incident light beam. The optical detector is also affixed to the sensor housing and detects a reflected light beam, said reflected light beam comprising a portion of the incident light beam reflected off of an object to be measured. The optical detector is further operable to generate an information signal containing information pertaining to one or more characteristics of the reflected light beam.
