Document Type and Number:
WIPO Patent Application WO/2019/116526
Kind Code:
A1
Abstract:
In order to reduce the number of components and the device size, a projection device comprises: a spatial light modulator having a display unit whereon a pattern corresponding to a display image is presented; a light source arranged to irradiate the display unit of the spatial light modulator with emission light; a projection optical system arranged on the optical path of the reflected light of the emission light incident on the display unit of the spatial optical modulator and projecting projection light with the high order component included in the reflected light removed therefrom; and a projection control unit that causes the display unit of the spatial light modulator to present a composite image that combines an image formed by a virtual lens that focuses the emission light incident on the display unit of the spatial optical modulator at a first focus position with the pattern corresponding to the display image, and controls the light source so that the display unit of the spatial light modulator is irradiated with the emission light.
