The physical thermal model for micro-bolometer under pulsed voltage bias is built, and the current responsivity expression of the micro-bolometer based on this physical thermal model is approximatively obtained in theory, which is in accordance with the numerical calculation of micro-bolometer current responsivity. Theoretical analysis shows that the current responsivity parameter is changed with voltage bias time, and this indicates that the current responsivity of micro-bolometer under pulsed voltage bias can be controlled by adjusting useful...
