Abstract

Fiber optic refractive index profile can be reconstructed from its mode field distribution. Toanalyzed this mode field image (digital image form), one formula, which derived from scalarwave equation, is needed to describe a relationship between the intensity and refractiveindex value as a radial function. This paper included numerical analysis to solve the secondorder differentiation and made the formula more suitable for computer process.Keywords: mode field distribution, scalar wave equation, refractive index, numericalanalysis

Abstract

Each person has a unique fingerprint and many research have been conducted to recognize thesefingerprints. Many applications have also been implemented related to fingerprint matching. This paperdiscusses on how good the Principal Component Analysis (PCA) which is combined with Hamming distance inrecognizing five fingerprints.Some experiments are conducted to get what is the best number of PCA vector in recognizing the fivehuman fingerprints data. The result of these experiments are also reported in this paperinally, the results of allexperiments are also be reported.Keywords: Principal Component Analysis, finger print, Hamming distance.
