Patent number: 7626705Abstract: A chromatically dispersive lens configuration may be utilized in optical pens for chromatic range sensing. The lens configuration may include a negative power doublet lens and a positive power lens portion. The Abbe numbers of lenses included in the positive power lens portion may be between the Abbe numbers of the two portions of the doublet lens. The relationship between the Abbe numbers of the materials used in two portions of the doublet lens is generally opposite to their relationship as used in standard doublet lenses of similar geometry. The doublet lens may have a negative spherical aberration which effectively cancels a positive spherical aberration that arises in the positive lens portion. In one embodiment all of the lens elements in the lens configuration are spherical lenses. The lens configuration can be implemented with dimensions which fit a standard commercial optical pen, while providing improved range sensing performance.Type: GrantFiled: March 30, 2007Date of Patent: December 1, 2009Assignee: Mitutoyo CorporationInventor: Eric Altendorf

Publication number: 20080062161Abstract: A method includes obtaining a measurement of a property of a light source, scanning light from the light source onto a surface, such that the light interacts with the surface, detecting light from the surface to create a picture element, and correcting the picture element with the measurement of the property. An apparatus includes a scanned beam display, the scanned beam display is configured to receive a signal and to scan the signal for viewing by a user. The signal is to contain picture element information. The picture element information includes information for a plurality of colors, wherein information for at least one color is corrected to substantially remove a perturbation to the picture element information, such that an image containing the picture element information will be substantially unchanged by the perturbation.Type: ApplicationFiled: July 19, 2007Publication date: March 13, 2008Applicant: Microvision, Inc.Inventors: Margaret Brown, Voytek Andron, David Skurnik, Eric Altendorf, Martin Kykta, Mark Holton, Clarence Tegreene, Christopher Wiklof

Publication number: 20070215797Abstract: A photoelectric encoder has a telecentric optical system in which a first lens and an aperture located at a focal position of the first lens are interposed between a main scale and a photoreceptor. At least a second lens is interposed between the aperture and the photoreceptor with a focus of the second lens on the aperture, thereby constituting a bilateral telecentric optical system. This makes it possible to improve the signal detection efficiency and increase the assembly tolerance.Type: ApplicationFiled: March 18, 2005Publication date: September 20, 2007Applicant: MITUTOYO CORPORATIONInventors: Toshitaka Shimomura, Shingo Nihommori, Miyako Mizutani, Eric Altendorf, Joseph Tobiason

Publication number: 20060284062Abstract: An illumination configuration for imaging-type optical encoders is provided. The illumination configuration generates uniform brightness images of scales and two-dimensional structures when utilizing telecentric imaging optics in the encoder readhead. In one embodiment, a desirable uniform irradiance distribution is created across the field of view by illuminating with a collimated or quasi-collimated beam, but insuring that the illumination is sufficiently incoherent that potential self-images arising from periodic structures on the scale are suppressed. In one embodiment, the ratio of an effective emitter size to a focal length of the collimating lens falls within a selected range, so as to assure relatively uniform illumination across the field of view and still provide sufficiently incoherent illumination.Type: ApplicationFiled: June 20, 2005Publication date: December 21, 2006Inventor: Eric Altendorf

Patent number: 6454945Abstract: This invention provides microfabricated systems for extraction of desired particles from a sample stream containing desired and undesired particles. The sample stream is placed in laminar flow contact with an extraction stream under conditions in which inertial effects are negligible. The contact between the two streams is maintained for a sufficient period of time to allow differential transport of the desired particles from the sample stream into the extraction stream. In a preferred embodiment the differential transport mechanism is diffusion. The extraction system of this invention coupled to a microfabricated diffusion-based mixing device and/or sensing means allows picoliter quantities of fluid to be processed or analyzed on devices no larger than silicon wafers. Such diffusion-based mixing or sensing devices are preferably channel cell systems for detecting the presence and/or measuring the quantity of analyte particles in a sample stream.Type: GrantFiled: November 1, 2000Date of Patent: September 24, 2002Assignee: University of WashingtonInventors: Bernhard H. Weigl, Paul Yager, James P. Brody, Mark R. Holl, Fred K. Forster, Eric Altendorf, Paul C. Galambos, Margaret Kenny, David Schutte, Gregory Hixson, Diane Zebert, Andrew Kamholz, Caicai Wu

Patent number: 6091502Abstract: A device and method for performing spectral measurements in flow cells with spatial resolution using a variable transmission optical filter having at least two areas with different optical properties. Light from a light source passes through the variable transmission filter to a flow cell containing a sample to be analyzed. The resultant light pattern is sensed by a detecting means, which analyzes the spectral properties of the sample within the flow cell.Type: GrantFiled: December 23, 1998Date of Patent: July 18, 2000Assignee: Micronics, Inc.Inventors: Bernhard H. Weigl, Eric Altendorf

Patent number: 5972710Abstract: A channel-cell system is provided for detecting the presence and/or measuring the presence of analyte particles in a sample stream comprising: a) a laminar flow channel; b) two inlets in fluid connection with the laminar flow channel for respectively conducting into the laminar flow channel (1) an indicator stream which may comprise an indicator substance which indicates the presence of the analyte particles by a detectable change in property when contacted with the analyte particles, and (2) the sample stream; c) wherein the laminar flow channel has a depth sufficiently small to allow laminar flow of the streams and a length sufficient to allow particles of the analyte to diffuse into the indicator stream to the substantial exclusion of the larger particles in the sample stream to form a detection area; and d) an outlet for conducting the streams out of the laminar flow channel to form a single mixed stream.Type: GrantFiled: March 31, 1997Date of Patent: October 26, 1999Assignee: University of WashingtonInventors: Bernhard H.
