摘要
The refractive index of an optical glass sample in the form of a wedge is measured by comparison with that of a reference liquid. This holographic technique can also be applied to the measurement of the refractive index of the immersion liquid, if the refractive index of the glass wedge is known. The accuracy of the method with respect to index matching, glass wedge preparation, and fringe position measurement on the interferogram is discussed.
