摘要：
The microbolometric voltage responsivity is theoretically obtained on the base of the thermal balance equation and the basic signal readout circuits for a typical microbolometer. The theoretical responsivity expression indicates that two vital factors to decide its value are the pulsed bias voltage and time. Some numerical calculations based on the theoretical voltage responsivity expression reveal the relationships between the microbolometric voltage responsivity and these two pulsed bias parameters. The pulsed bias parameters optimization for...
