Title:
PROJECTION DEVICE AND INTERFACE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/129279
Kind Code:
A1
Abstract:
In order to project an image from which zero-order light is removed without adding extra pixels or modulation elements, and without adding distortion or reducing luminance, the projection device according to the present invention is provided with: a phase modulator for modulating the phase of incident laser light; a Fourier transform lens for performing Fourier transformation of laser light, the phase of which is modulated by the phase modulator; a mirror for reflecting the laser light which is Fourier transformed by the Fourier transform lens, the mirror being provided on a surface of image formation by the Fourier transform lens; and a projection lens for magnifying and projecting, as projection light, the light reflected by the mirror; the mirror directing zero-order light included in the Fourier-transformed laser light in a direction other than to the projection lens and reflecting the light not including zero-order light toward the projection lens.
