摘　　要：为使干涉仪能在低温下正常可靠的工作,从低温下波面畸变、动镜倾斜及分束器的性能变化几个方面讨论了低温对干涉调制度的影响.介绍了减小低温对干涉调制度影响的措施,为确定傅里叶光谱仪干涉系统光学机械零件的材料、加工准确度、装夹方式、装调要求以及干涉仪的动态控制准确度等提供了参考依据.The effects of wavefront distortion, moving mirror tilt and property parameters change of beam splitter on modulation efficiency were analyzed and some measures were introduced so that the interferometer can work reliably in low temperature. The experiment results show that this study can help decide material, fixing mode and dynamic control precision of optical （mechanical） components for interferometer system in a fourier spectrometer.
