Noncircular aperture imaging system
| DWPI Title: Noncircular aperture imaging system, has imaging objective comprising optical element, and image processor for generating composite image of scene based upon light received by imaging objective at set of different times |
| 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. |
| Use: Noncircular aperture imaging system. |
| Advantage: The system processes image frames of non-uniform spatial resolution to generate composite images with uniform spatial resolution. |
| Novelty: The system has an imaging objective comprising a first optical element having a noncircular aperture. An anamorphic optical system receives light from the first optical element, where the anamorphic optical system increases a field of view of the imaging objective. An image processor generates a composite image of a scene based upon light received by the imaging objective at a set of different times, where the imaging objective includes different rotational orientation with respect to the scene at each of the different times, the composite image comprises a first region and a second region, and the second region includes higher spatial resolution than the first region. |
