Optical path difference
http://www.microscopyu.com/techniques/polarized-light/principles-of-birefringence WebThe optical path difference (OPD) is defined as the difference between the aberrated and the ideal unaberrated wavefronts. The OPD is positive if the aberrated wavefront leads the ideal unaberrated wavefront as shown in Fig. 2. Also, if the aberrated wavefront curves in more than the unaberrated wavefront, the OPD is positive.

WebApr 8, 2024 · Actual path length or Geometric length is simply the real length travelled by the light in the medium. Note: For clarity, we can prove the formula for the optical path length as follows: The distance travelled by light in the medium is. d g = v m × t. but now, the distance the length would have travelled in vacuum in the same time would be. 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.
