  • As for the nonlinear effects of infrared focal plane arrays intensity response, a nonlinear calibration method is proposed based on single wavelength laser. Experimental equipment is designed for measuring, and the nonlinear calibration curve of the focal plane array is obtained through the measuring equiprment. Experimental results show that this method aviods the influence of infrared focal plane arrays spectral response nonuniformity, and meets the requirement of generality and practicability of the device in the engineering technology, which ensures the high accuracy of measurement as well as simpleness.
