title: Fiber optic linear displacement sensor based on a variable period diffraction grating.
abstract: A high accuracy wavelength encoding fiber optic sensor is shown to display surprisingly little sensitivity to temperature or optical source drift. Average measurement error of 0.1 % full scale has been demonstrated over a displacement range of 10 mm.
