摘要：
In this article, the practical structure of two-color microbolometers for uncooled infrared detection was considered, a mathematical model to calculate infrared absorptance was described. The optical characteristic of multilayer structure consisting of Nitride (SiNx) infrared absorber film/ Vanadium (VOx) heat sensitive film/ SiNx support film/ the first optical resonant cavity/ a tunable reflecting Al micromirror/ the second optical resonant cavity /a bottom electrode made up of Al was investigated. According to optical admittance matrix theory, relation between infrared absorber film thickness, the first optical resonant cavity of two-color microbolometer and infrared absorptivity was simulated by MATLAB software.
