Title: Method to smooth photometric variations across multi-projector displays

Abstract

A method is provided to smooth photometric variations across multi-projector displays. Photometric calibration is performed to generate a luminance attenuation map (LAM) for each projector. An image for each projector is modified using the luminance attenuation map (LAM) for each projector to provide image correction in real time. In the photometric calibration step a digital camera is used to measure the color response of the multi-projector display. Using the generated luminance attenuation map (LAM) for each projector for image correction in real time smoothes out distracting color variations across the multi-projector display while maximizing a perceived dynamic range of the display.

Methods and measurement engine for aligning multi-projector display systems

Patent Hereld, Mark; Judson, Ivan R.; Stevens, Rick L.

An image pattern description is stored and tiled display test pattern images are captured. The stored image pattern description and at least one captured tiled display test pattern image are used to identify a tile array placement and layout; a tile registration measurement; and a dot grid measurement providing measured dot grid positions. At least one captured tiled display test pattern images and the measured dot grid positions are used for calculating tile-to-camera maps and a camera-to-mural map. The tile-to-camera maps and the camera-to-mural map are used to generate control and correction data.

Thin display optical projector

Patent Veligdan, James T [Manorville, NY]

An optical system (20) projects light into a planar optical display (10). The display includes laminated optical waveguides (12) defining an inlet face (14) at one end and an outlet screen (16) at an opposite end. A first mirror (26) collimates light from a light source (18) along a first axis, and distributes the light along a second axis. A second mirror (28) collimates the light from the first mirror along the second axis to illuminate the inlet face and produce an image on the screen.

System for obtaining smooth laser beams where intensity variations are reduced by spectral dispersion of the laser light (SSD)

Patent Skupsky, Stanley [Rochester, NY]; Kessler, Terrance J [Rochester, NY]; Short, Robert W [Rochester, NY]; ...

In an SSD (smoothing by spectral dispersion) system which reduces the time-averaged spatial variations in intensity of the laser light to provide uniform illumination of a laser fusion target, an electro-optic phase modulator through which a laser beam passes produces a broadband output beam by imposing a frequency modulated bandwidth on the laser beam. A grating provides spatial and angular spectral dispersion of the beam. Due to the phase modulation, the frequencies ("colors") cycle across the beam. The dispersed beam may be amplified and frequency converted (e.g., tripled) in a plurality of beam lines. A distributed phase plate (DPP) inmore » « less

Apparatus for sensing patterns of electrical field variations across a surface

Patent Warren, William L [Arlington, VA]; Devine, Roderick A. B. [Paris, FR]

An array of nonvolatile field effect transistors used to sense electric potential variations. The transistors owe their nonvolatility to the movement of protons within the oxide layer that occurs only in response to an externally applied electric potential between the gate on one side of the oxide and the source/drain on the other side. The position of the protons within the oxide layer either creates or destroys a conducting channel in the adjacent source/channel/drain layer below it, the current in the channel being measured as the state of the nonvolatile memory. The protons can also be moved by potentials createdmore » « less
