Title: Phase plate for linear to elliptic polarization conversion
Inventor: ASANUMA NOBUHISA
IPC: G02B27/28
Filed: 1983-10-25
Abstract: PURPOSE:To obtain a linear-elliptic polarization conversion phase plate which is less influenced by variation in the incidence angle of a light beam by slanting an Y axis by an angle beta of refraction to a normal N to a surface of the phase plate. CONSTITUTION:The phase plate is so designed that the optical path of the refraction of an extraordinary light beam determined by the angle alpha of incidence to the surface of a crystal plate is coincident with the Y axis. This is realized by slanting the Y axis by the angle beta of refraction to the normal N to the surface of the phase plate. Consequently, the wave front of the extraordinary light beam separated by the refraction of the incident light entered the phase plate travels on minimum points of the influence of variation in said angle alpha of incidence, i.e. the Y axis, so variation in the phase difference P from the ordinary light beam is minimized. The same effect is obtained even when the Y and X axes are converted.
