查询词典 array

Considering the spectrometer with an array detector,a Gaussian-shaped calibration spectral line's integral sampling model is set up.The condition on which the peak position changes upon the impact of the detector spectral response is studied.And the limitation for the detector spectral response not to shift the peak position to another pixel is given.The limitation's mathematical expression for a spectrometer with a grating is deduced.
