非吸收多层膜传输时的相移显示为波数的单调递减函数，其平均斜率与涂层的光学厚度成正比。研究了反射相移的两种极限情况：一种是相位随波长单调增加，另一种是相位振荡。在已知辐射反射率和Blaschke因子的情况下，反射时的相移可由kramers - kroni型关系推导。讨论了与这些因素有关的折射率剖面特征。(C) 1997美国光学学会。
The phase shift upon transmission of a nonabsorbing multilayer is shown to be a monotonically decreasing function of the wave number, with an average slope proportional to the optical thickness of the coating. Two limiting situations of the phase shift upon reflection are examined: In one the phase monotonically increases with wavelength, and in the other the phase oscillates. The phase shift upon reflection is derivable from Kramers-Kronig-type relationships, provided the radiant reflectance and the Blaschke factors are known. Characteristic features of the refractive-index profile related to these factors are discussed. (C) 1997 Optical Society of America.
