Response model of resistance-type microbolometer

摘要: There are certain limitations in the application of uncooled focal plane array (FPA) detectors owing to shortage response model that transforms bias voltage analog output at a constant radiation power; Moreover, affects input gain. In this study, we established microbolometer through examining detection theory and heat balance equation under condition pulse bias. establishment process, simplified order acquire simple answer. The experimental data show that, full variable range voltages, biggest difference between experiment is about 0.7 K. This can reflect real responses microbolometers with only small differences, which acceptable engineering applications.
