Diffraction Grating Spectroscopy

Applied Optics, 1969
The present state of grating spectroscopy is reviewed with special emphasis on the far ir. The review includes the discussion of the properties of diffraction gratings, the intensity distribution among different orders of echelette gratings, Wood anomalies, ir and submillimeterwave filters, detectors, grating spectrometers with thermal sources, rules ...

Diffraction gratings and optical aberrations

Applied Optics, 1984
The effects introduced by a plane diffraction grating on the diffracted wave front when a quasi-plane beam incides on it are calculated. Effects not previously discussed appear.

On the Theory of Imperfect Diffraction Gratings

Journal of the Optical Society of America, 1948
The “dynamical” theory of gratings originally developed by Rayleigh and Voigt is applied to derive the intensity of the light diffracted in various directions by an imperfect grating of finite area. The problem is reduced to the numerical solution of a system of linear equations by an approximation method in which “ghosts” and high order spectra are ...

Diffraction gratings

1992
Abstract A ‘conventional’ spectrometer receives light through an entrance slit, separates out (disperses) the frequencies in the light by some means, and focuses each frequency to its own place at the output. When the light contains discrete frequencies, a set of bright lines is seen at the output, each of which is an image of the ...
