In one embodiment, a video display system employs an array of ribbon light modulators having a reflective surface configured to reflect or diffract a beam. The beam may have a wavelength suitable for displaying a video image. The reflective surface may comprise an aluminum alloy suitable for receiving the beam, which may have a relatively high power density. In one embodiment, a method of displaying a video image comprises impinging a beam on a portion of a reflective surface of a light modulator. The beam may have a wavelength suitable for displaying a video image, and the reflective surface may comprise an aluminum alloy.

Robust reflective surface for light modulators

Techniques for determining large deformation of layered or graded structures to include effects of body forces such as gravity, electrostatic or electromagnetic forces, and other forces that uniformly distribute over the structures, support forces, and concentrated forces. A real-time stress monitoring system is also disclosed to provide in-situ monitoring of a device based on the large deformation analytical approach. A coherent gradient sensing module, for example, may be included in such a system.

Determining large deformations and stresses of layered and graded structures to include effects of body forces

The current invention is directed to devices and systems with patterned reflective surfaces. The reflective surfaces are patterned with primary reflective regions and gap regions. The gap regions provide for separation between reflective material within adjacent primary reflective regions. The separation between reflective material reduces atomic flux which can lead to the depletion of the reflective material within regions of the reflective surface that are exposed to an intense light source. The primary reflective regions are preferably formed from a reflective material such as aluminum, silver, gold or platinum. The gap regions are left vacant or deposited with second material which is non-reflective, reflective or semi-reflective. The patterned reflective surface is preferably formed on a micro-structure, such an elongated ribbon. The patterned ribbon structure is preferably one of a plurality patterned ribbon structures in a grating light valve device.
