Abstract

In recent years, a new fiber position sensor based on wavelength encoding plane variable-line-space gratings is developed and has attracted more and more interest. In this paper the theoretical background to the fiber position sensor concept is briefly described. The large slope groove density distribution variable-line-space grating with holographic recording is used in fiber position sensor. The preliminary results obtained were quite noteworthy. Due to the unevenness of the incident light intensity in different wavelength, the diffractive intensity of different position change quickly. The diffraction wavelength curve of the system is given. The resolution of the position sensor is also discussed in this paper.
