Change in spatial coherence of light on refraction and on reflection

Abstract

A theory of refraction and reflection of partially coherent electromagnetic beams has been recently developed. In this paper, we apply it to study the change in spatial coherence caused by refraction and by reflection more fully. By considering a Gaussian Schell-model beam, we show that the change is, in general, dependent on the angle of incidence.

“…In classical optics, coherence theory [1][2][3] is a subject that continuously receives innovative contributions from countless authors, both within the scalar [4][5][6][7][8][9][10][11] and vectorial realm [12][13][14][15][16][17][18][19][20][21], including nonstationary states [22][23][24][25][26].…”
