WebThe van Cittert Zernike (vCZ) theorem is a well- -known result of classical statistical optics [1]. A generalized form of this theorem is sometimes referred to as the reciprocity relationship between the intensity distribution and the degree of (spatial) coherence of a quasi-monochromatic beam in the source and the detector planes [2]. This WebApr 20, 2024 · ( 2) a generalized van Cittert–Zernike theorem as the original one describes the evolution of the cross-spectral density of light, generated by an extended incoherent source, on free space propagation [ 1 ]. The optical imaging system that we employ does not merely consist of simple lenses and stretches of free space.
