摘要
本文从计算光程差入手,讨论了透射光栅的刻纹面与非刻纹面不平行时对光波波长测量的影响,并给出了完全消除这一影响的一种测量方案及相应的调节方法。
Starting with the calculation of the path difference of light,the influence of penetra- ble grating,the engraved and non-engraved surfaces of which are non-parallel,on the determination of light wave length is discussed in this paper.And a measuring process which can eliminate the influence completely is given.Finally,the corresponding adjustment of performing this measurement is de- scribed.
