Abstract: A microlens array for obtaining a multi-focus plenoptic image includes a first individual microlens array where first microlenses having one focus distance are arranged on a first substrate, a second individual microlens array where second microlenses having the same or different focus distances are arranged on a second substrate, the second individual microlens array being stacked on the first individual microlens array having the same or different focus distances, and a third individual microlens array where third microlenses having the same or different focus distances are arranged on a third substrate, the third individual microlens array being stacked on the second individual microlens array. As seen in a plane, an array form of the first to third microlenses are configured with two microlenses, which are spaced apart from each other by an interval corresponding to one microlens in a vertical axis and a horizontal axis, on one of the first to third substrates.

Abstract: Provided are an apparatus and method for adjusting an optical axis. In the apparatus, an iris diaphragm and a quadrant photodiode (QPD) are used to align optical axes of an optical system of the apparatus so that optical transmission efficiency between an optical transmitter and an optical receiver can be increased. Since a hole of the iris diaphragm can be adjusted to be small, a beam larger than a light-receiving area of the QPD can be included in the light-receiving area, and optical axis alignment is facilitated accordingly. When the QPD and the iris diaphragm are applied to the apparatus, it is possible to simultaneously perform data transmission, tracking, and optical axis alignment. An optical fiber end surface and optical axes of lenses arranged in parallel are aligned in the apparatus so that alignment between two terminals can be easy and reception efficiency can be increased.

Abstract: The present disclosure can effectively improve an angular image resolution and a spatial image resolution compared to the related art by solving a problem of a plenoptic image based on a microlens array according to the related art. In the case of the microlens array according to the related art, microlenses having different numerical apertures (NAs) and F # (F numbers) or focal lengths are positioned on one substrate. However, in the present disclosure, two or more microlens arrays having different NAs and F # are stacked in a layer form (all the microlenses of each microlens array are formed in the same F # and the same NA) to allow various F # and various NAs to be implemented, and thus an image of an object is formed on a sensor plane at different positions. Accordingly, a spatial resolution and a depth resolution increase.
