Paper Abstract

Optical transfer functions (O.T.F.s) of a simple plane-grating monochromator were determined by both of Fourier transforms of line profiles and direct measurements. The ray-tracing method and a spectrogram of monochromatic rays were used to determine line spread functions, and their Fourier transforms gave the O.T.F.s. The direct measurement of O.T.F.s were performed by measuring responses of light beams having sinusoidal spectra, which were produced using a Fabry-Perot interferometer. A blurred spectrum of Na-D doublet was satistactorily corrected by means of these O.T.F.s. The result using the directly measured O.T.F. was the best.
