Abstract

The phase of the complex degree of temporal coherence of visible light is shown to be deducible from a three-beam interference experiment without any wavelength-scale accuracy on measuring a pathlength difference. Methods are discussed where the phase is obtained from the amplitude of rapid oscillations of the corresponding interferogram.
