Abstract:

An instrument is described which measures the azimuth of elliptically poloarized light and optical phase differences to about 2pi x 10 to the minus 6th power. The principle involved is that the constants of an elliptical vibration can be determined by transforming it into a linear vibration by passage through a doubly refracting plate quarter-wave plate and then measuring the azimuth of the emergent vibration. The sample surface producing the elliptical polarization is horizontal which allows extreme and repeatable accuracy in setting up the instrument. The method of use is briefly described. The final adjustment, which is that of rotating an analysing prism, may be done manually or with slightly less accuracy, by automatic rotation with a digital read out. Author
