    Abstract:

    Aiming at the nonlinearity of photoresponse characteristic in infrared focal plane arrays,a approach of nonuniformity correction for IRFPA,named "curve-beeline" correction,was proposed,and the correction formula was given.The simulation results show that it has perfect performance of high precision,and less calculation.Only a few parameters are needed to storage and it is easy to implement by hardware circuit.
