Abstract: An image display device includes: a laser light source; a first lens that converges a laser beam emitted from the laser light source, in a first direction; a second lens that converges the laser beam emitted from the laser light source, in a second direction perpendicular to the first direction; a spatial light modulator irradiated with the laser beam that has passed through the first lens and the second lens; a first vibrator that vibrates the first lens along a first vibration plane; and a second vibrator that vibrates the second lens along a second vibration plane non-parallel to the first vibration plane.

Abstract: An optical device includes: a light source part configured to project illumination light toward a sensing region; a photodetector configured to receive reflected light of the illumination light reflected on the sensing region; and a condenser mirror. The condenser mirror has a through hole through which the illumination light from the light source part passes and an optical axis of the light source part and an optical axis of the condenser mirror are aligned with each other. A reflection surface of the condenser mirror has a shape obtained by cutting out a columnar body extending in a projection direction of the illumination light, with a spheroid whose rotation axis is a major axis. The photodetector is disposed in a direction toward a first focal position of the condenser mirror. The sensing region is set in a direction toward a second focal position of the condenser mirror.

Abstract: A road surface condition prediction system includes a collector which collects pieces of moisture information on moisture on a road surface obtained by detecting the moisture on the road surface of a road on which moving bodies travel, and pieces of position information each indicating a position on the road surface at which the moisture is detected, one or more of the pieces of moisture information and one or more of the pieces of position information being collected from each of the moving bodies; and a predictor which predicts a moisture condition of a target road surface at a time after a time at which moisture on the target road surface is detected, based on moisture information obtained by detecting the moisture on the target road surface, the target road surface being a road surface at a position indicated by at least one of the pieces of position information.
