Title:
OPTICAL DEVICE AND OPERATION INPUT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/114102
Kind Code:
A1
Abstract:
An optical device that is provided with: a light-guiding plate that guides light within a plane that is parallel to an emission surface of the light; and a sensor that is provided on a side that is opposite the emission surface with respect to the light-guiding plate, and that is for detecting an object that is located on the emission-surface side by means of light that passes through a rear surface, which is on the side opposite the emission surface, and through the emission surface. The light-guiding plate has a plurality of light-convergence parts that have respective optical surfaces that receive light that is guided by the light-guiding plate and cause emission light to be emitted from the emission surface in directions that substantially converge at a convergence point in space or in a convergence line or that substantially diverge from a convergence point in space or from a convergence line. The plurality of light-convergence parts has different convergence points or convergence lines, and an image is formed in space on the emission-surface side from the aggregation of the plurality of convergence points or convergence lines.
