Appl. No.:

09/301947

Inventors:

Allen H. Tanner - Sandy UT
Calvin L. Simmons - Bountiful UT

Assignee:

Evans Sutherland Computer Corporation - Salt Lake City UT

International Classification:

G09G 500

US Classification:

345 31, 345 32, 345 10, 345 14, 345 17, 345 27, 345545, 348399, 348440, 348571, 348572

Abstract:

An apparatus for converting analog stroke display signals representing electron beam generated stroke traces into raster display information for producing a raster-scan image display. The apparatus includes a sampling circuit for sampling the analog stroke display signals to produce pixel data representing sub-pixel locations covered by the stroke traces. A frame buffer is coupled to the sampling circuit to temporarily store pixel data. A filter is coupled to the frame buffer for calculating brightness of pixels based upon the amount of coverage of the pixels by a stroke trace. In addition, a raster-scan display device is coupled to the filter for receiving the pixel data from the filter to produce a raster-scan image.

Filed:

Mar 5, 2001

Appl. No.:

09/799164

Inventors:

Jesse Anderegg - Salt Lake City UT
Bret Winkler - South Jordan UT
Allen Tanner - Sandy UT

Assignee:

Evans Sutherland Computer Corporation - Salt Lake City UT

International Classification:

G02B 626

US Classification:

385 30, 385147

Abstract:

A system and method for polishing an optical fiber with a polishing lap. The system comprises a substrate, an optical fiber disposed on the substrate so as to be outwardly curved, and an electrical conductor disposed over the outward curve of the optical fiber. A voltage source is connected to the electrical conductor, and the polishing lap is configured to initially abrade the electrical conductor to cause severance thereof. The position of the polishing lap when the electrical conductor is severed represents a reference point approximately indicating the surface of the optical fiber. A detector connected to the electrical conductor detects a change in voltage therein, indicating severance of the electrical conductor, and subsequently monitors the polishing depth relative to the reference point.

Appl. No.:

10/127987

Inventors:

Allen H. Tanner - Sandy UT
Dennis F. Elkins - Draper UT
Cameron C. Farmer - Sandy UT
Yuri S. Grapov - Sandy UT

Assignee:

Evans Sutherland Computer Corporation - Salt Lake City UT

International Classification:

H01S 313

US Classification:

372 30, 372 25

Abstract:

A rapidly oscillating laser light source is produced that exhibits extended pulse duration having a substantially uniform amplified output. A pulsed beam of laser light having a given wavelength, frequency, duration and intensity is produced such that the pulse shape is controlled. The pulsed beam is amplified using a fiber amplifier which exhibits inherent changes in amplifier gain at the frequencies of interest. The fiber amplifier is continuously pumped. A feedback signal is provided with the amplified pulse characteristics and is used to adjust the pulse shape of the pulsed beam of laser light before amplifying, such that the intensity is changed over the pulse duration to generate a substantially uniform amplified output during each pulse.

Appl. No.:

Allen H. Tanner - Sandy UT

Assignee:

Evans Sutherland Computer Corporation - Salt Lake City UT

International Classification:

G02F 101

US Classification:

359238, 359276, 359278

Abstract:

A device for the passive conversion of one format to another includes: a laser light source at a predetermined frequency, a line converter configured to produce a fan of light, a movable lens configured to collimate the fan of light, and an array of light modulators placed such that the collimated light is incident on a portion of the light modulators. Vertical pixels of an input image are reproduced on either 1, 2, 3, etc, adjacent light modulators depending on the target image size to produce a modulated light column. Any discrepancy between the modulated light column height and the target image height is compensated for using a zoom lens. The modulated light column is then reflected to a display surface. An entire image is produced by changing the state of the array of light modulators to correspond with each of the vertical columns of the image and sweeping the vertical columns across the display surface. The method accomplishes the format conversion passively, in that, simple calculations are performed only once for each input image size.

Abstract:

A method and device for the nonlinear combination of laser light which produces a beam of uniform intensity, high spatial purity, and high conversion efficiency. The method includes emitting a laser light from a tunable distributed feedback fiber laser having both thermal and piezoelectric control elements which produces a laser light at a given frequency, wavelength, and intensity; converting the laser light in a nonlinear resonator which uses a nonlinear optical crystal for frequency conversion or mixing; and measuring the resonant frequency of the nonlinear resonator and adjusting the laser light frequency using both the thermal and piezoelectric elements of the fiber laser light source to match the resonant frequency conditions within the nonlinear resonator.

Abstract:

A wide angle display system includes a linear array projector, a curved display surface, and a two-sided, substantially planar scanning mirror. The projector is configured to project an image along an optical axis to the scanning mirror. The scanning mirror continuously rotates about an axis substantially in the plane of the mirror, so as to reflect and scan the image onto the display surface.

Abstract:

A panoramic display system includes a curved projection screen, a panoramic projector, and a substantially conically shaped barrier. The projector is configured to project an image onto the projection screen from a projection point located substantially above the projection screen. The conical barrier has a base disposed toward the bottom of the projection screen, and an apex region disposed toward the projection point. The barrier blocks scattered light from reflecting from portions of the curved screen to other portions thereof.
