HgCdTe LWIR 576 x 6 FPA PREPARED BY LOOPHOLE TECHNIQUE

HgCdTe long wave infrared (LWIR) 576 x 6 focal plane assembly (FPA) is a core assembly of high performance thermal imager. In this study, the design of HgCdTe LWIR 576 x 6 FPA was completed, and the 576 x 6 focal plane arrays were prepared with loophole technology. The integrative 576 x 6 FPA was obtained by packaged in Dewar/Stirling cooler assembly. Parameters measurements show that the typical detector average peak detectability is 1.79 x 10(11) cm Hz(1/2)/W, the uniformity is 14.6%, and the died detective element is 6.0%. The thermal imaging of the 576 x 6 FPA has also been demonstrated in the laboratory.
