Simple spectral reduction algorithm used for the echelle spectrometer.

Applied Optics, 2018
The structure of the echelle spectrometer equipped with a prism cross-dispersion element is very complex because of the nonlinear interaction between the prism and the echelle grating, which makes it difficult to extract the wavelength information from ...
