Publication number: 20070129601Abstract: The present invention provides scanning beam devices that have one or more detectors positioned within a housing of the device. The detector(s) may be disposed anywhere within the housing to receive light reflected from the target area. In one embodiment, an optical assembly of the device transmits a first portion of the reflected light to a scanning element, and a second portion of the reflected light to the detectors. In another embodiment, the optical assembly is configured to transmit substantially all of the reflected light to the scanning element. In such embodiments, the scanning element will be adapted to allow the light to exit the scanning element and impinge on the detector(s) within the housing.Type: ApplicationFiled: February 2, 2007Publication date: June 7, 2007Applicant: University of WashingtonInventors: Richard Johnston, Charles Melville

Publication number: 20070091426Abstract: The present invention provides methods and systems for scanning an illumination spot over a target area. The present invention removes stored energy from a scanning element to stop the scanning element from vibrating and to substantially return the scanning element to its starting position so as to enable high frame rates.Type: ApplicationFiled: December 19, 2006Publication date: April 26, 2007Applicant: University of WashingtonInventors: Richard Johnston, Charles Melville, Cameron Lee

Publication number: 20070019906Abstract: Methods and system for counterbalancing accelerations and/or torques caused by actuation of an actuation element and a scanning element. A scanning beam device may comprise a counterbalance to generate forces and/or torques that are substantially equal and substantially opposite to the forces and/or torque generated by the scanning of the actuation element.Type: ApplicationFiled: July 21, 2005Publication date: January 25, 2007Applicant: University of Washington UW Tech Transfer - Invention LicensingInventor: Charles Melville

Publication number: 20060226231Abstract: The present invention provides methods, software, and systems that allow a scanning beam device to create full or partial color images using sequential color methods. The methods of the present invention may use sequential color concepts to improve image generation without increasing scan rates while using light source modulation rates that are much less than conventional methods.Type: ApplicationFiled: March 29, 2005Publication date: October 12, 2006Applicant: University of WashingtonInventors: Richard Johnston, Cameron Lee, Charles Melville

Publication number: 20060077121Abstract: Apparent distance of a pixel within an optical field of view is determined. Incoming light is scanned along a raster pattern to direct light for a select pixel onto a light distance detector. The distance is sampled for each pixel or for a group of pixels. The light distance detector includes a concentric set of rings sensors. The larger the spot of light corresponding to the pixel, the more rings are impinged. The diameter of the spot is proportional to the distance at which the light originated (e.g., light source or object from which light was reflected). Alternatively, a variable focus lens (VFL) adjusts focal length for a given pixel to achieve a standard spot size. The distance at which the light originated correlates to the focal length of the VFL.Type: ApplicationFiled: November 28, 2005Publication date: April 13, 2006Applicant: University of WashingtonInventors: Charles Melville, Michael Tidwell, Richard Johnston, Joel Kollin
