ABSTRACT:
A temperature stable displacement sensor with fine resolution having a housing with a radiation source, preferably an LED for generating radiation in the near-infrared region, a lens for collimating the LED radiation into a beam spaced along the axis of the housing from the LED by a distance equal to the focal length of the lens, a reflector for intercepting and reflecting the beam, the reflector comprising a first fluid having a relatively high reflection coefficient and a second fluid supported by the first having a substantially greater viscosity than the first fluid, and a radiation detector located adjacent the radiation source for receiving the reflected beam and generating an electrical signal representative of the angular position of the reflected radiation beam incident thereto with respect to a reference axis.
