Filed:

May 18, 2000

Appl. No.:

09/574733

Inventors:

Robert W. Corrigan - Los Altos CA

Assignee:

Silicon Light Machines - Sunnyvale CA

International Classification:

G02B 642

US Classification:

385 4, 385 31, 385116, 359618

Abstract:

An image projector projects an image onto a display screen and includes a laser source unit, an optical fiber, and a projector head. The projector head includes a light modulator and an optical projection arrangement. The optical fiber couples a laser illumination to the light modulator of the projector head from the laser source unit. The light modulator modulates the laser illumination to produce an array of pixels. The optical projection arrangement projects the array of pixels onto the display screen to produce the image on the display screen. Preferably, the image projector is a color image projector. In the color image projector, the laser source unit includes red, green, and blue lasers, which illuminate first, second, third light modulators. The first, second, and third light modulators produce red, green, and blue arrays of pixels, which the optical projection arrangement projects onto the display screen to produce a color image.

Assignee:

Silicon Light Machines Corporation - Sunnyvale CA

International Classification:

G02F001/00

US Classification:

359237, 385 16

Abstract:

One embodiment pertains to an apparatus for wavelength-selective switching and equalization of an incoming multiplexed signal having a plurality of wavelength components. The apparatus includes a first controllable light modulator, a second controllable light modulator, and a lens system. The first controllable light modulator controllably deflects a first set of the wavelength components and controllably reflects a second set of the wavelength components. The wavelength components in the second set are mapped onto separate sections of the second controllable light modulator by the lens system and are controllably reflected by the second controllable light modulator.

Abstract:

A method, system, and display apparatus, for securely transmitting and displaying visual data, are disclosed. The method of securely transmitting and displaying the visual data includes encrypting the visual data, transporting encrypted visual data to a display apparatus, decrypting the encrypted visual data within the display apparatus, and displaying the visual data as a visual image. The step of decrypting the visual data includes maintaining an electronic version of the visual data within circuit elements that are substantially inaccessible. The system for securely transmitting and displaying the visual data includes an encryption apparatus, means for transporting the encrypted visual data, and the display apparatus. The display apparatus includes circuit elements that are substantially inaccessible. The circuit elements include a decryption circuit for decrypting the encrypted visual data, which forms the visual data within the display apparatus. The circuit elements also include a display circuit for displaying the visual data as a visual image. The circuit elements are configured such that an electronic version of the visual data is maintained within the circuit elements.
