Paper Abstract

A thickness measurement system of ultra-thin metal foils using differential white light interference has been investigated, where a data processing scheme, using wavelet transform has been carried out. The analysis of simulation result indicates that this method has high accuracy and can be applied in the course of actual measurement.
