Apparatus for producing color effects

摘要

Apparatus for producing color effects includes a source of polychromatic light, a transparent linear-polarizer medium located to receive the polychromatic light and to output linearly polarized light, a transparent phase-rotating dispersive medium located to receive the linearly polarized light and to rotate the angle of polarization thereof as a function of wavelength to thereby produce color separation of the polarized light, and a transparent linear-analyzer medium located to receive the light from the dispersive medium at a selected angle to output a selected color thereof.
