Paper Abstract

We have implemented an infrared array camera for high-background, ground-based astronomical imaging in the mid-infrared spectral region from 5 to 27 microns. The camera is built around a 20 X 64 element Si:As Impurity Band Conduction (IBC) device manufactured by GenCorp Aerojet Electronic Systems Division. Observations with the camera on a 1.5 meter telescope (Mt. Lemmon Observing Facility, Tucson, Arizona) yield a noise- equivalent flux density (NEFD) of 23.5 mJy min-1/2 arcsec-2 at (lambda) equals 10 micrometers , (Delta) (lambda) equals 1 micrometers , and a readout frame rate of 366 Hz. We discuss the design and implementation of the camera and operational procedures for observation in a high-background environment (e.g. background subtraction and flat-fielding). We also present sample images obtained with our camera.
