In the orthogonal wavelet transformation coding, it is to make use of wavelet frequencysplitting that may deal with data, and then get the better result of compression.
利用正交小波变换进行小波分频特性分析处理，得到了较好的压缩结果。

The measurement result is optimized by using the rotating grating for splitting laser light and producing frequency shift to determine the fluid direction.
