Paper Abstract

An infrared staring mode imaging sensor was designed to operate with the NASA Infrared Telescope Facility (IRTF) at Mauna Kea, Hawaii. The sensor has a 0.5 arc sec spatial resolution over a 10 arc sec field and is matched to the f/35 focal ratio of the telescope. The focal plane device is a back-side illuminated Schottky infrared charge-coupled device (IRCCD) mosaic with a photoresponse from 1 to 5upm. Astronomical observations are reported at 2.2 um where the IRCCD quantum efficiency is substantially greater than values normally reported for the 3.4 to 4.2 um thermal imaging band.
