M. Yoshida et R. Shintani, CONTROL OF THE INTENSITY OF POLARIZED-LIGHT FOR ENTIRE VISIBLE-LIGHT REGION USING COMPOSITE HALF-WAVE PLATE, JPN J A P 1, 34(8A), 1995, pp. 4274-4275
The half-wave plate has been used to control the intensity of linearly
polarized light in experiments. However this plate can be applied onl
y to monochromatic light, because of the dependence of the action of t
he half-wave plate on wavelength. A new composite half-wave plate can
be designed for the entire visible light region using two phase plates
. Satisfied condition of the composite half-wave plate using two phase
plates is obtained on the Poincare sphere.
