Abstract

A fiber optic position sensor suitable for use in hazardous environments is described. The sensing element is a diffraction grating having a linear variation in period over its length. When illuminated with a broadband optical source at a fixed angle of incidence, linear translation of the grating causes a linear shift in the wavelength of the detected signal collected at a fixed angle. Maximum error of 0.1% over a range of 25 mm has been demonstrated. The sensor is compared to traditional linear position sensors.
