摘要：

Microwave Imaging Reflectometry (MIR) has been developed for measuring two-dimensional electron density fluctuations on many Tokamaks. A MIR system with 96 pixels (12 poloidal x 8 radial) has been fabricated for EAST tokamak. In the paper, we present the evaluation results in laboratory bench test with details, including performance of the electronic system and optics. With an artificial target as the real plasma cutoff layer, it has been proved that the EAST MIR system has the capability to reconstruct the correct corrugated shape of cutoff layer.
