Noncircular aperture imaging system

Abstract

Various technologies pertaining to an imaging system with a noncircular aperture are described herein. An imaging objective with a noncircular aperture and an anamorphic lens is used to capture a plurality of image frames of a scene. Each image frame is captured at a different rotational orientation of the imaging objective with respect to the scene. Each image frame has a non-uniform spatial resolution. A composite image of the scene is generated based upon the image frames. The composite image comprises a first region that has a spatial resolution that is approximately the same as a spatial resolution of an image generated using a circular objective with a diameter equal to the largest dimension of the noncircular aperture, and a second region with a lower spatial resolution.
