| Abstract: | The joint effect of nonlinear response characteristics and transmitting power fluctuation on scattering measurement is analyzed. This joint effect may produce rather large error for scattering measurement alone, and the reason is discussed in detail. To eliminate the error, a mathematic model of calibration is established. Then, a fusion method of scattering and radiometric measurement is developed based on a scatterometer and radiometer combined system. Simulation result reveals improvement in data accuracy and expansion of measurement range by the fusion method. |
