Abstract:
Partitioning the pupil reduces the degree of baseline redundancy, and therefore improves the quality of images that can be obtained from the system. A practical realization of this approach uses an aperture partitioning element at an aft optics pupil of the optical system. This paper describes on-sky testing of a new aperture partitioning element that is completely reflective and reconfigurable. The device uses four independent, annular segments that can be positioned with a high degree of accuracy without impacting optical wavefront of each segment. This mirror has been produced and is currently deployed and working on the 3.6 m telescope. A comparison to a non-partitioned image will illustrate the utility of the hardware in improving image quality.
