Optical element and optical device

Abstract

The present technology relates to an optical element and an optical device that enable resolution of a light image to be increased at a position according to the position of the light image to be detected in an optical element that forms an image without a lens. The optical element includes an optical element plate that includes, in part, a light transmission part forming a light image of an object by light from the object, the light having passed through a transparent zone that transmits light, and that blocks light in a portion other than the transparent zone, in which the transparent zone is formed such that resolution of a light image formed in a direction different from a normal direction of a plate surface of the optical element plate with respect to the light transmission part is higher than resolution of a light image formed in the normal direction.
