Spatial & Temporal Coherence - NTUA
van Cittert-Zernike Theorem states that the spatial coherence area A c is given by: where d is the diameter of the light source and D is the distance away. Basically, wave -fronts smooth . out as they propagate away ; from the source. Prof. Elias N. Glytsis, School of ECE, NTUA ; 15 .

Zernike Polynomials - University of Arizona
wp.optics.arizona.eduZernike Polynomials 1 Introduction Often, to aid in the interpretation of optical test results it is convenient to express wavefront data in polynomial form. Zernike polynomials are often used for this purpose since they are made up of terms that are of the same form as the types of aberrations often observed in optical tests (Zernike, 1934).
