To increase the output signal-to-noise ratio of microbolometric focal plane array, the microbolometric bias optimization is crucial. The bias influence on the microbolometric responsivity is theoretically analyzed and numerically calculated, and the microbolometric responsivity can be optimized according to these theoretical analysis and calculated results. Some kinds of microbolometric noises are also theoretically discussed, from which the microbolometric noise can be theoretically derived to be related to the microbolometric bias parameter through numerical calculation. The bias optimizatio...
