Paper Abstract

The Cryogenic Limb Array Etalon Spectrometer (CLAES) will fly on the NASA Upper Atmosphere Research Satellite (UARS) in 1991. CLAES uses solid-state focal plane arrays to detect emission from the earth's atmosphere over the infrared wavelength range 3.5 to 13 μm. This paper discusses the design of the focal plane detector assembly and compares calculated performance with measurements. Measurements were made of focal plane noise and responsivity as functions of frequency (2 to 500 Hz) and temperature (12 to 19 K), pixel-to-pixel and across-array crosstalk, and linearity over a dynamic range of 105. The measurements demonstrate that the arrays satisfy the science requirements, and that, in general, there is reasonable agreement between the measurements and the analytical model.
