摘要：
The electron cyclotron emission imaging (ECEI) instrument is widely used to study the local electron temperature (T-e) fluctuations by measuring the ECE intensity I-ECE proportional to T-e in tokamak plasmas. The ECEI measurement is often processed in a normalized fluctuation quantity against the time averaged value due to complication in absolute calibration. In this paper, the ECEI channels are relatively calibrated using the flat T-e assumption of the sawtooth crash or the tearing mode island and a proper extrapolation. The 2-D relatively calibrated electron temperature (T-e,T-rel) images are reconstructed and the displacement amplitude of the magnetohydrodynamic modes can be measured for the accurate quantitative growth analysis.
