System and Method for Efficiently Delivering Rays from a Light Source to Create an Image
First Claim
1. A system, comprising:
- a polarizing beamsplitter operable to split one or more unpolarized rays received from an illumination source into a first polarized component and a second polarized component, the first polarized component and the second polarized component having orthogonal polarizations to each other;
a half-wave plate operable to rotate the second polarized component to the same polarization as the first polarized component; and
a lens group operable to pass the first polarized component to a target plane as a first polarized ray, and further operable to separately pass the second polarized component to the target plane as a second polarized ray.

Abstract
In accordance with one embodiment of the present disclosure, a system may include a polarizing beamsplitter for splitting one or more unpolarized rays received from an illumination source into a first polarized component and a second polarized component, the first polarized component and the second polarized component having orthogonal polarizations to each other. The system may also include a half-wave plate for rotating the second polarized component to the same polarization as the first polarized component. The system may further include a lens group for passing the first polarized component to a target plane as a first polarized ray, and further for separately passing the second polarized component to the target plane as a second polarized ray.
