Paper Abstract

HgCdTe (MCT) 256 X 4 TDI long wave IRFPA and SPRITE are both preferable devices of high performance IR imaging systems. As we know, IRFPA is better than 60, 120-element long wave photoconductive detectors. But the comparison between 256 X 4 TDI IRFPA and 8 X 4 sprite has never been discussed. This paper is focused on the comparison between the output SNR of the two detectors because they have different spectrum response. Generally speaking, a 8 X 1 sprite is only equal to 100-element photoconductive detector. But the results of our research show that 8 X 4 sprite detector can function similarly to 256 X 4 TDI IRFPA when applied in IR imaging systems whose object is in ambient temperature.
