Patent number: 11889173Abstract: A topographical measurement system uses an imaging cartridge formed of a rigid optical element and a clear, elastomeric sensing surface configured to capture high-resolution topographical data from a measurement surface. The imaging cartridge may be configured as a removable cartridge for the system so that the imaging cartridge, including the rigid optical element and elastomeric sensing surface can be removed and replaced as a single, integral component that is robust/stable over multiple uses, and easily user-replaceable as frequently as necessary or desired. The cartridge may also usefully incorporate a number of light shaping and other features to support optimal illumination and image capture.Type: GrantFiled: May 17, 2021Date of Patent: January 30, 2024Assignee: GelSight, Inc.Inventors: Janos Rohaly, Edward H. Adelson

Patent number: 11846499Abstract: A retrographic sensor includes a clear elastomer substrate, a deformable reflective layer, and a contact surface with an array of rigid, non-planar features formed of a material or a pattern of particles to mitigate adhesion to a target surface while permitting the egress of trapped air around a region of interest. This combination of features permits the contact surface of the sensor to more closely conform to the target surface while physically transferring the topography of the target surface to the deformable layer for imaging through the substrate.Type: GrantFiled: March 5, 2021Date of Patent: December 19, 2023Assignee: GelSight, Inc.Inventors: Edward H. Adelson, F. Richard Cottrell

Publication number: 20230263414Abstract: An optomechanical sensor system is provided. The system can include a patient-worn surface displacement system comprising a deformable surface configured to be positioned against the patient adjacent to a superficial artery thereof, a plurality of optical markings disposed on the deformable surface, and an actuator configured to apply a pressure to hold the surface displacement system against the patient such that spatiotemporal movement of the superficial artery causes corresponding movement of the deformable surface and the plurality of optical markings. The system further includes an optical system which includes an imaging system, illumination, and with or without mirrors configured to visualize the plurality of optical markings at an oblique angle. The system determined the spatiotemporal movement of the superficial artery based on the received plurality of images and determine a cardiopulmonary parameter associated with the patient based thereon.Type: ApplicationFiled: August 10, 2021Publication date: August 24, 2023Inventors: Edward H.

Publication number: 20140104395Abstract: Methods of and systems for three-dimensional digital impression and visualization of objects through an elastomer are disclosed. A method of estimating optical correction parameters for an imaging system include pressing an object of known surface topography against an elastomer and imaging a plurality of views of the surface topography of the object through the elastomer. The method also includes estimating a three-dimensional model of the object based on the plurality of views and estimating optical correction parameters based on a known surface topography of the object and the estimated three-dimensional model. The optical correction parameters correct distortions in the estimated three-dimensional model to better match the known surface topography.Type: ApplicationFiled: October 17, 2013Publication date: April 17, 2014Applicant: GELSIGHT, INC.Inventors: Janos ROHALY, Micah K.

Patent number: 8411140Abstract: A tactile sensor includes a photosensing structure, a volume of elastomer capable of transmitting an image, and a reflective skin covering the volume of elastomer. The reflective skin is illuminated through the volume of elastomer by one or more light sources, and has particles that reflect light incident on the reflective skin from within the volume of elastomer. The reflective skin is geometrically altered in response to pressure applied by an entity touching the reflective skin, the geometrical alteration causing localized changes in the surface normal of the skin and associated localized changes in the amount of light reflected from the reflective skin in the direction of the photosensing structure. The photosensing structure receives a portion of the reflected light in the form of an image, the image indicating one or more features of the entity producing the pressure.Type: GrantFiled: June 19, 2009Date of Patent: April 2, 2013Assignee: Massachusetts Institute of TechnologyInventor: Edward H.

Patent number: 5818972Abstract: A system for, and method of, enhancing a digitized image signal according to a helper signal architecture are described. The architecture includes an analysis filter, responsive to a digitized image signal, for filtering the digitized image signal, corresponding to a first frequency band, to produce a first frequency band signal. The first frequency band signal is then applied to a point operator, which modifies the first frequency band signal in accordance with a non-linear characteristic. The non-linear characteristic includes a first region having a negative slope for low amplitude input signals. The non-linearity further includes a second region having a positive slope for informational components of an input signal so that informational components of the first frequency band signal cause the point operator to produce a modified signal having components that relate to the input signal according to the positive slope.Type: GrantFiled: June 7, 1995Date of Patent: October 6, 1998Assignee: RealNetworks, Inc.Inventors: Bernd Girod, Edward H.
