Abstract

Optical characteristic of an infrared focal plane array (FPA) based on thermo-optic effect is analyzed using film optics method. Then, an optimizing film assembly of thermo-optic infrared focal plane array (TOFPA) described as air|<HL>²30.1H<LH>²16L|substrate is obtained with its temperature sensitivity 6.23% K^-1. Furthermore, the influence of substrate material, device package and absorption is discussed. The results show that the temperature sensitivity of the film assembly of TOFPA is modulated by 16.4%, 8.99%, -11.3 %, and -0.6% with the influence of glass substrate, silicon substrate, glass package and optical absorption of film material, respectively.
