Abstract
Some embodiments pertain to an optical zoom system. The optical zoom system includes a first inward-facing surface that is at least partly reflective and a second inward-facing surface that is at least partly reflective. The optical zoom system further includes a first aperture that includes a plurality of sub-apertures which are positioned around at least a portion of an outer periphery of one of the first and second inward facing surfaces. Each sub-aperture includes an optically powered element. The optical zoom system further includes a second aperture that exists proximate a central region of the optical zoom system. Light is reflected on the first and second inward facing surfaces as the light travels between the first aperture and the second aperture such that the light is optically combined into a single image before exiting the second aperture.
