Method for calibrating spectral characteristics of a spectral analyzer and a spectral analyzer applying said method |
摘要 |
The differences between the center wavelength and half bandwidth of the spectral sensitivity of each pixel of a sensor array in a spectral analyzer to be calibrated and the preprovided respective standard values of the center wavelength and the half bandwidth are expressed as functions of a pixel number (linear functions), and coefficients that define the functions are determined based on the pixel outputs of the sensor array obtained by measuring predetermined wavelength standards. The center wavelength and half bandwidth of each pixel are estimated from the differences obtained from the functions with the determined coefficients and the standard values.
