Abstract

A high performance 8 to 12 µm 72-element (Hg,Cd)Te detector array has been built for an advanced difffaction-limited serial-scanned FLIR system. The avelzage peak detect it for the array is 1.7 x 1011 cm Hz ^1/2 /W which results in a cumulative detectivity (~ rn D avg.) of 1.4 x 10¹² cm Hz ^1/2 /W . The cumulative detectivity controls system sensitivity. The cumulative D* for this array is over 2.3 times higher than a modular FLIR array with 180 elements and a better than average peak detectivity of 4.5 x 1010 cm Hz ^1/2 /W or a cumulative detectivity of 0.6 x 10¹⁰ cm Hz ½/W.
