Path Difference

the difference in the optical paths of two light rays having common initial and terminal points. The concept of path difference is of fundamental importance in accounting for the interference and diffraction of light. Calculations of the distribution of luminous energy in optical systems are based on a determination of the path difference of the rays, or pencils of rays, passing through the systems.
