Abstract

A compensated fiber optic displacement sensor (CFODS) was introduced and its transmission properties at room temperature (293 K) and liquid nitrogen temperature (77 K) were analyzed comparatively. The analysis shows that this sensor can effectively eliminate environmental effects, so it can be used to measure displacement at a large temperature range. The results of measuring suspension micro-displacement of superconducting rotor at liquid helium temperature (4.2 K) demonstrate that it is feasible to measure micro-displacement of objects using the CFODS with measuring resolution about 10μm at low temperature, which gives some useful reference for the application of the CFODS to cryogenic environment.
