Paper Abstract

Although charge coupled staring mosaic FLIRs offer ultimate sensitivity improvement factors of 30 or more over existing scanning FLIRs, dynamic range and uniformity limitations restrict realizable improvement. By dealing only with background shot noise, charge handling, and uniformity, the basic limitations are determined without complicating the analysis with additional electronics reset noise, transfer efficiency, fast interface state noise, and other possible additional noise degradations. It is also shown that describing the detector operation as "BLIP" does not in itself imply that the best sensor electronics configuration is being utilized. Ultimate Noise Equivalent Temperature Difference (NETD) of .0012°C and .0003°C are predicted for 3-5 m and 8-5 im sensors. Further studies of atmospheric thermal uniformity statistics may be required to determine the ultimate usable sensitivity.
