摘要
This disclosure describes a novel lens system having an entrance pupil at a location matching, or nearly matching, the eye's optical system entrance pupil. The described lens system is significantly thinner than a single-aperture lens with matched entrance pupil and is achieved by using an array of camera elements. Each camera element contains camera optics called “lenslets” and a sensor (e.g., an image or depth sensor), where a lenslet can include one or more lens elements (e.g., a compound lens). Individual camera elements can be arranged such that THEIR optical axes intersect at, or near, the eye's entrance pupil location. In addition, each camera element's field-of-view (FOV) corresponds to a small sector of a large FOV. The FOVs of adjacent camera elements can be non- or slightly-overlapping so that a wide-angle image can be formed by concatenation of the individual camera element images.
