Abstract

White light interferometric sensing systems are very attractive for application in smart structures due to the fact that they read out the absolute path differences from the transducers so that calibration schemes and device history do not have to be used. The basic output from such systems consists of arrays of data containing complex interference patterns. In this paper, the output of such sensing systems is simulated and used as a common basis for the comparison of a number of different signal processing algorithms that could be used to reduce the raw output to a more usable form.
