primary standards of wavelength 原始波长标准
secondary standards of wavelength 次级波长标准
The main algorithm of spectrum analysis are the base 2 FFT and the spectral calibration that can be detected in the two standards to the location within the wavelength calibration achieved.
光谱获取的算法主要由基2 - FFT和光谱标定实现，光谱标定是通过在可探测波长内取两个标准位置来计算中心波长准确位置的。
