...Young’s two-slit apparatus Transverse coherence is typically measured using Young’s two slit apparatus.(10) This method measures the coherence of one part of the image against another by interfering portions of the beam with each other....

...A planar and secondary source generating Gaussian Schell-model beams is a beam which displays Gaussian distributions of both the optical intensity and the degree of transverse coherence.(11,12) The degree of spatial coherence measures the correlations between the amplitudes of the optical field at two points across the beam and it is the normalized form of the transverse spatial coherence function, more precisely the cross-spectral density function....
