  • Patent number: 10782392
    Abstract: A scanning optical system, includes a mirror unit having a first mirror surface and a second mirror surface which incline to a rotation axis; and a light projecting system having a light source. A light flux emitted from the light source is reflected on the first mirror surface of the mirror unit, thereafter, reflected on the second mirror surface, and then, projected so as to scan in a main scanning direction onto an object in accordance with rotation of the mirror unit. The light flux emitted from the second mirror surface becomes a plurality of spot lights on the object side, and the plurality of spot lights are arranged along a direction intersecting with the main scanning direction.

  • Publication number: 20160041311
    Abstract: Provided is a compound optical system that can obtain high-resolution images by solving the problem of aberration in a field-of-view separation-type optical system, and that enables a super thin image pickup device to be achieved. Also provided is an image pickup device using the compound optical system. With respect to the image pickup range of a central individual-eye lens, by narrowing the image pickup range of a peripheral individual-eye lens, the field curvature amount at the image pickup region can be reduced, and therefore, the eccentricity amount of the lens surface (or the lens group) can be reduced. As a result, an individual-eye lens with little defocus and good image forming characteristics can be obtained, and a compound optical system with favorable image forming characteristics can be configured.
