title: Complex degree of coherence measurement for classical statistical fields.
abstract: We propose a new method for measuring real and imaginary parts of the complex degree of coherence of a classical field obeying Gaussian statistics. Our method is based on mixing incoherently a coherent Gaussian beam, a local oscillator, and the statistical field. We stress that our approach is especially beneficial for revealing the complex degree of coherence of inhomogeneous two-dimensional fields. As an illustration, we report the complex degree of the coherence measurement of a complex Gaussian-correlated beam. Our method can find applications in image transmission and recovery.
