7 May 2003 Image enhancement of polarized images using wavelet orthogonality and biorthogonality
Author Affiliations +
Polarization in optical waveguides is always an aspect of optical loss and consequently impacts device performance. Wavelet image processing allows a means to detect optical signals buried under noise. Orthogonality is an essential element in wavelet bases. Wavelet transforms are orthogonal. They can also be biorthogonal. Wavelet image processing will be applied to laser beam propagation in lithium niobate and nonlinear polymer waveguides to achieve detection of signals below noise and a better understanding of polarization as an aspect of device performance.
