Abstract

Results of the application of wavelet transform for signal processing in white-light interferometry are reported. The mother wavelet frequency is chosen to be the light-source correlogram 1's, and accurate phase measurements are obtained from simple correlation computations. The fringe envelope is also addressed and permits a complete analysis of coherence-limited fringe patterns. Miscalibrations of phase shift and mean wavelength are also considered.

摘要

报道了小波变换在白光干涉测量信号处理中的应用结果。母小波频率被选为光源相关图1的频率，并通过简单的相关计算获得了精确的相位测量结果。还讨论了条纹包络，它允许对相干极限条纹图案进行完整分析。同时也考虑了相移和平均波长的校准误差。
