%X The mathematical techniques are made for the nonuniformity correction of IRFPA based on radiation source scaling.It indicates that the complicated engineering problem is belonged to the function interpolation or function fitting.Based on this principle,some dependent correction algorithms such as cubic spline function interpolation,B-spline function least squares fitting and polynomial least squares fitting were derived.Experimentation indicates that these algorithms can highly adapt to the broad dynamic range and non-linearity of IRFPA and are suitable for engineering applications with fast computing speed and high calibration precision.
