| 摘要 |
<p>The present invention provides an enhanced polarized light source for a display system. In one embodiment, the invention includes a light source (11) to produce light having multiple polarization states, a relay optical system (23) to relay light imaged onto the relay optical system onto a display (17), an optical imaging element (25) to image light from the light source onto the relay optical system (23), a polarization separator (34) to direct light of a first polarization to a first portion of the optical imaging element and light of a second orthogonal polarization to a second portion of the optical imaging element, and a polarization conversion element (35) between the optical imaging element and the relay optical system to receive light having the second polarization from the optical imaging element and convert its polarization to the second polarization.</p> |
