Whipple Observatory, Amado, AZ; (c) Dep. of Astronomy, UMass, Amherst, MA; (d) MIT Lin | | Abstract: | The tip-tilt correction system at the Infrared Optical Telescope Array (IOTA) has been upgraded with a new star tracker camera. The camera features a backside-illuminated CCD chip offering doubled overall quantum efficiency and a four times higher system gain compared to the previous system. Tests carried out to characterize the new system showed a higher system gain with a lower read-out noise electron level. Shorter read-out cycle times now allow to compensate tip-tilt fluctuations so that their error imposed on visibility measurements becomes comparable to, and even smaller than, that of higher-order aberrations. | | Source: | arXiv, astro-ph/0408038 | | Services: | Forum | Review | PDF | Favorites | |
