To insure reliable and accurate measurement results of mirror angular displacement for COIL resonator, indirect measurement was found using electronic autocollimator. Measurement results show that thermal radiation is main reason of mirror angular displacement and results in the beam spot drift for COIL. Adopting measures, the mirror angular displacement and the beam spot drift are obviously reduced. Experiments verify that the measurement method is reasonable and reliable.
