Abstract
An infrared camera system has been developed to be used with a ground-based telescope. The camera system includes reimaging optics with a cold Lyot stop, provision for spectral filtering, and a detector/mux chip mounting assembly. The purpose of the camera is to provide a breadboard facility for the demonstration of advanced focal plane array (FPA) detector technologies in an actual field test environment. The initial demonstration described in this paper is with an impurity band conduction (IBC) extrinsic silicon FPA. The optical system is designed to couple to an f/4.2, 100-inch focal length Newtonian telescope in the 9.5 to 11.5 micron wavelength band. Versatility is offered by adapting to a variety of FPAs packaged in leadless chip carriers, interchangeable optics, and cryogenic dewar configurations. A LN2, LHe dewar was used because of its simplicity and freedom from vibration and EMI. Image generation is accomplished using an oscillating mirror in the optical path external to the dewar. Digitized FPA output is recorded for image reconstruction and analysis. The first application for the camera will be observations of missile plumes of launches from the Eastern Test Range at KSC and Cape Canaveral.
