Abstract

The problem of determining the phase ϕ of the complex degree of coherence γ of a light beam from measurements of its modulus |γ| is considered. If a reference beam of light with an exactly known complex degree of coherence is available, then the phase ϕ may be determined from an additional experiment in which the two beams are superimposed.
