Laser On-Line Thickness Measurement Technology Based on Judgment and Wavelet De-Noising

Abstract:

Lithium battery coating thickness is measured by sensor using laser triangulation. The algorithm based on threshold judgment and multi-scale wavelet is realized for noise high-frequency reduction of lithium battery film thickness systems. The result shows that compared with the unique multi-scale wavelet de-noising, the method applies to different lengths and discontinuous of coating thickness measurement. .
