The geometric length is simply the physical distance the light travels. The optical path length is important because it allows us to find out what the phase of the light will be at any point, whereas the geometrical length doesn't. c1 = n * c2.

WebSep 19, 2013 · If the optical path difference of both interferometer’s arms is equal or is multiple of 2π, there is constructive interference and the intensity of interference fringes is maximum. The above model refers to a free space Michelson interferometer. WebThe optical path difference is the product of two terms: the thickness (t) and the difference in refractive index (n). The OPD can often be quite large even though the thickness of the object is quite thin. On the other hand, when the refractive indices of the specimen and the surrounding medium are equal, the OPD is zero even if the specimen ...
