Abstract

A far-infrared interferometer which can test ground surface is presented. Both theoretic analyses and experimental results show that the interferometer has the accuracy of λ/100 (RMS). This accuracy is able to meet the requirement of grinding primary mirror. In addition, the design and system performance of the infrared system is presented.
