Abstract

In measuring the width of a laser beam, the scale of the object to be measured is much smaller than the measuring device. With a wavelet transform, on the other hand, the scale can be progressively reduced, since scale is part of the mathematics of wavelets. Wavelet signal processing (noise reduction, edge detection and multiscale feature detection) will be applied to laser beam diagnostics (focal point, divergence, and collimation).
