Abstract
An image display apparatus and a method for recapturing off-state light are provided. The image display apparatus includes a spatial light modulator, a reflector, and an integrator element. The spatial light modulator, in response to a light beam, selectively modulates the light beam along a first path to form a first path light beam. The reflector reflects the first path light beam to form a reflected light beam. The integrator element collects and reflects the reflected light beam to form a recapture light beam. Further, the spatial light modulator modulates the recapture light beam along a second path to form an image on a screen.

An image display apparatus, comprising:
- a spatial light modulator, in response to a light beam, configured to selectively modulate said light beam along a first path to form a first path light beam;
- a reflector configured to reflect said first path light beam to form a reflected light beam;
- and
- an integrator element configured to collect and reflect said reflected light beam to form a recapture light beam;
- wherein said spatial light modulator modulates said recapture light beam along a second path to form an image on a screen.
A method for displaying image with recapture of off-state light, comprising:
- providing a light beam;
- selectively modulating said light beam along a first path by a spatial light modulator to form a first path light beam;
- reflecting said first path light beam to from a recapture light beam;
- and
- modulating said recapture light beam along a second path by said spatial light modulator to form an image on a screen.
