摘要:
An image display system and associated method for image displaying The system includes an image source configured to generate image light, projection optics configured to project the image light, and a polarizing beam splitter optically coupled to the projection optics and configured to propagate into a first optical path first polarized light having a first polarization and to propagate into a second optical path second polarized light having a second polarization The system includes a quarter wave converter disposed in the first optical path and configured to rotate the first polarization by a quarter phase as the first polarized light first passes through the quarter wave converter, and includes a reflective screen disposed in the first optical path and configured to reflect rotated first polarized light from the quarter wave converter back through the quarter wave converter for further quarter phase rotation.
