Paper Abstract

A fibre optic interferometric sensor for the analysis of surface texture is presented, which incorporates optical fibre links to achieve a remote and passive sensing head. A synthetic heterodyne signal recovery scheme based upon modulating the frequency of the laser diode source was used to generate a high frequency optical carrier ideal for in-process surface profiling. It is demonstrated that the system is capable of both differential and absolute measurements, a resolution of .O.1 nm/ IHz was achieved.
