生成正弦黑白条纹，可以修改正弦条纹的周期，视场大小等-Generating sinusoidal black-and-white stripes, sinusoidal fringe cycle can be modified, depending on the field size, etc.

基于matlab对脉搏波进行单周期提取，能够很好的提取并且算出单周期波形的平均面积。-Matlab based on single-cycle pulse wave extraction, can be a good area to extract and calculate the average single-cycle waveform.
