| Abstract: | Nonuniformity of IRFPA with CTIA readout circuit comes from detector diode,input offset voltage of operational amplifier in CTIA and integration capacitor of readout circuit.They are analyzed,calculated and tested in the paper.The best bias region of detector diode in which IRFPA has minimum nonuniformity is obtained in the end. |
