WebDec 12, 2024 · Based on this model, the interference optical system is studied to illustrate the cause of the interference fringes. Furthermore, the influencing factors of the light intensity distribution are analyzed and an adjustment method for the interference fringes is proposed, which helps to simplify the assembling and calibrating operations. WebJan 9, 2024 · The locus of points of constant intensity are phase fronts, the locus of constant phase. 2) The Huygens wavelets generated at every point on a spherical wave do interfere. The result of the superposition is uniform (fringeless) pattern on a screen. – garyp Jan 9, 2024 at 13:56
