Correlation functions of light inside the transformed system. The incident light is a Gaussian Schell-model beam [12] with a beam width of 400 μm and a coherence length of 100 μm at the wavelength of 0.6328 μm. a Surface height, b Real values of the correlation function of the incident light, imaginary parts being zero, c Phase of the correlation function of light leaving the Kinoform lens, d Phase of the correlation function of light leaving the paraxial negative lens
