US 2017/0248783 A1 · COLLIMATING LIGHT EMITTED BY A FIBER VIA AN ARRAY OF LENSLETS ON A CURVED SURFACE

Abstract

An embodiment is directed to an optical element arrangement including at least one optical element. A first optical element includes a fiber and a curved surface. The fiber emits light beams during oscillation at different angular positions relative to a system axis of the first optical element. The curved surface includes an array of lenslets. Each of the lenslets in the array of lenslets is configured to receive light beams from the fiber that are emitted within a particular range of the first curved surface and to collimate the light beams received by the lenslet at a lenslet-specific field angle relative to the system axis. In other embodiments, one or more additional optical elements with respective fibers can be deployed as part of the optical element arrangement, and any of the optical elements in the optical element arrangement may include multiple curved surfaces with respective lenslet arrays.
