Title:
OPTICAL DEVICE AND OPTICAL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2016/114104
Kind Code:
A1
Abstract:
An optical device that is provided with; a light-guiding plate; and a light source that sends light to the light-guiding plate from different positions in a direction that is orthogonal to the light-guidance direction of the light-guiding plate. The light-guiding plate has light-convergence parts that have respective optical surfaces that cause emission light to be emitted from an emission surface in directions that substantially converge on 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 light-convergence parts have different convergence points or convergence lines, and an image is formed in space from the aggregation of the convergence points or convergence lines. There are more light-convergence parts that cause emission light to be emitted from the emission surface in directions that substantially converge within a prescribed range that includes points that are separated from the emission surface by a first distance or that substantially diverge from within a prescribed range from points that are separated from the emission surface by the first distance than there are second light-convergence parts that cause emission light to be emitted from the emission surface in directions that substantially converge within a prescribed range that includes points that are separated from the emission surface by a second distance that is longer than the first distance or that substantially diverge from within the prescribed range that includes points that are separated from the emission surface by the second distance.
