ABSTRACT:
A diffraction grating has incident and emitting side gratings respectively formed on front and rear faces of a diffraction substrate composed of a transparent plane-parallel plate. A pitch .LAMBDA..sub.1 of the incident side grating, a pitch .LAMBDA..sub.2 of the emitting side grating, a refractive index n.sub.1 of the diffraction substrate, a thickness t of the diffraction substrate, and incident angle .theta..sub.1 of light incident to the incident side grating, an angle .theta..sub.2 of diffraction within the diffraction substrate, an emission angle .theta..sub.3 of light emitted from the emitting side grating, a distance T from the emitting side grating to a face for receiving the emitted and diffracted light, and a wavelength .lambda. of the light are set to satisfy the following conditions. ##EQU1##
