Wavelet Analysis of PK2600 Measurement Data on Core-Rod

The Core Rod made by Plasma Chemical Vapor Deposition process is measured by PK2600 for Refractive Index Profile. The measurement data is very important to justify the core rod quality. A method based on DWT is presented in this paper to discover some information which is difficult to emerge according to conventional way. The analysis result can be used to optimize the core-rod making process.
