Abstract
A displacement sensor enabling us to perform measurements under moderate feedback has been designed with a resolution up to 40 nm. Its performance can be optimized by using the wavelet transform when the signal is disturbed by electromagnetic fields, mechanical coupling, or speckle effect. By determining the repeatability and the reproducibility of this sensor, we have also demonstrated that this measuring device is suitable for statistical process control when an interval of tolerance of ±300 nm is required.
