UAH-P-13009-Field-Separated Multi-Path Telescope

Docket: UAH-P-13009


Two-mirror telescope designs image a small well-corrected circular field-of-view (FOV) about the optical axis of the two mirrors. Three-mirror designs use a primary, secondary, and tertiary mirror to increase the range of the FOV, but this range is still limited. One type of three-mirror telescope has a very well-corrected annular zone FOV and does not form a complete circle; image quality at the center can be considerably worse. The absence of this complete circular field limits the FOV because the optimum annular zone is not present. There is a need for better correction, specifically in the reduced annular field.

Researchers at UAH have developed a set of optical systems that separate the light into different paths, allowing for precise image quality correction in several field regions. These light paths are independently corrected to form a high quality FOV over any portion of the entire circular FOV.
