Issue Date: | 2016 | Volume: | Optical and Infrared Interferometry and Imaging V | Editors: | Malbet, Fabien; Creech-Eakman, Michelle J.; Tuthill, Peter G. | Series: | PROCEEDINGS OF SPIE | Number: | 9907 | First Page: | 990742 | Abstract: | This paper describes the current opto-mechanical design of AGP, a mission designed for astrometric verification of General Relativity (GR) and competing gravitation theories by means of precise determination of light deflection on field stars, and of orbital parameters of selected Solar System objects. The optical concept includes a planar rear-view mirror for simultaneous imaging on the CCD mosaic detector of fields of view also from the direction opposite to the Sun, affected by negligible deflection, for the sake of real time calibration. The precision of astrometric measurements on individual stars will be of order of 1 mas, over two fields separated by few degrees around the Sun and observed simultaneously. We describe the optical design characteristics, with particular reference to manufacturing and tolerancing aspects, evidencing the preservation of very good imaging performance over the range of expected operating conditions. | Conference Name: | Optical and Infrared Interferometry and Imaging V | Conference Place: | Edinburgh, United Kingdom | Conference Date: | 26 June - 1 July 2016 | URI: | http://hdl.handle.net/20.500.12386/28536 | URL: | https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9907/1/AGP-Astrometric-Gravitation-Probe-optical-design-report/10.1117/12.2232769.short?SSO=1 | ISSN: | 0277-786X | ISBN: | 9781510601932 | DOI: | 10.1117/12.2232769 | Bibcode ADS: | 2016SPIE.9907E..42R | Fulltext: | open |
