本程序可读取Yokogawa 光谱仪多个数据文件(CSV格式)并寻峰。数据文件为多个光栅串的测试光谱。串联光栅波长间隔等距，可确定等距串联光栅的中心波长和峰值强度，将数据存入mat file 使用前请设置若干重要参数 【wl_start】 【wl_end】 【FBGs_num】 【Min_PowerValue】【Peaks_seperation】 其他相关变量说明 【OSA_data】 所读入的光谱全图 里面可能包含更宽的波长 【OSA_data_FBGs】截取光栅串所在波长区间，由【wl_start】 【wl_end】决定 导出的数据文件为 FBGs.mat， 其中所保存的 重要变量为 【FBGs_peaks】 【FBGs_peaks】 第1列：峰值所在序号； 第2列：横轴-光栅串中心波长值； 第3列：纵轴-光栅串光强值(This program can read multiple data files (CSV format) of Yokogawa spectrometer and find peaks. The data file is a test spectrum for multiple grating strings. The length of the series grating wavelength interval can determine the central wavelength and peak intensity of the isometric series grating. Before using the data into mat file, please set up some important parameters [wl_start] [wl_end] [FBGs_num] [Min_PowerValue] (Peaks_seperation] other related variables said the spectrum read by [OSA_data] The full graph may contain a wider wavelength [OSA_data_FBGs] to intercept the wavelength range of the grating string, and the data file derived by [wl_start] [wl_end] is FBGs.mat, in which the important variable is the [FBGs_peaks] [FBGs_peaks] first column: the peak in the sequence number; the second column: the transverse axis grating string. Center wavelength value; third column: longitudinal axis grating intensity value)
