Patent number: 10935364Abstract: Disclosed are systems and methods to extract information about the size and shape of an object by observing variations of the radiation pattern caused by illuminating the object with coherent radiation sources and changing the wavelengths of the source. Sensing and image-reconstruction systems and methods are described for recovering the image of an object utilizing projected and transparent reference points and radiation sources such as tunable lasers. Sensing and image-reconstruction systems and methods are also described for rapid sensing of such radiation patterns. A computational system and method is also described for sensing and reconstructing the image from its autocorrelation. This computational approach uses the fact that the autocorrelation is the weighted sum of shifted copies of an image, where the shifts are obtained by sequentially placing each individual scattering cell of the object at the origin of the autocorrelation space.Type: GrantFiled: March 18, 2019Date of Patent: March 2, 2021Inventor: Lyle G.

Publication number: 20030072011Abstract: A method and apparatus for combining multiple views of an object using a three-dimensional surface profiling apparatus, which compensates for depth of field effects, is described. The apparatus utilizes a single source and a single receiver to acquire the multiple views of small objects. A lens or a system of lenses adjust the focal plane to account for the shorter distance that the radiation will travel along a first optical path than along a second optical path, so that both images are in focus on the detector at substantially the same time. For large objects, a three-dimensional surface profiling apparatus utilizing more than one camera is used.Type: ApplicationFiled: October 8, 2002Publication date: April 17, 2003Inventor: Lyle G.

Patent number: 5900936Abstract: An apparatus and method for measuring the surface deformation or displacement in objects. In one embodiment the apparatus includes an interference pattern generator which projects an interference pattern onto a detector mounted to the surface which is to be measured. As the surface deforms, the detector moves and sweeps across the interference pattern. By noting the changes in the light intensity, the deformation or displacement in the surface at the detector may be determined. In another embodiment, both the detector and the interference pattern generator are located on the surface and as the surface deforms, the relative change in the surface at the detector and the relative deformation or displacement of the surface at the interference pattern generator may be determined. In another embodiment a plurality of detectors and interference pattern generators are positioned to map the deformation or displacement of the surface at many locations on the surface.Type: GrantFiled: October 23, 1997Date of Patent: May 4, 1999Assignee: Massachusetts Institute of TechnologyInventors: Lyle G.

Patent number: 5870191Abstract: Apparatus and methods of measuring position information, typically the depth coordinate, of a point on the surface of an object. In one embodiment, the apparatus includes two sources of radiation positioned to illuminate the point on the surface of the object with radiation from each of the sources. The radiation from each of the sources is coherent with respect to the radiation from the other source. A control system changes the phase of the radiation from at least one of the sources relative to the phase of the radiation from the other source as measured at the point on the surface of the object. A detector is positioned to receive radiation scattered by the point and a processor, in communication with the detector, calculates position information in response to the change in phase of the radiation from the source and the received radiation scattered by the point on the surface of the object.Type: GrantFiled: February 12, 1996Date of Patent: February 9, 1999Assignee: Massachusetts Institute of TechnologyInventors: Lyle G.

Patent number: 5811826Abstract: A method and apparatus for remotely sensing the orientation of an object takes advantage of the fact that, for flat surfaces, a change in radiation frequency illuminating the object produces a global translation at the detector plane of the speckle pattern reflected from the object. An object is illuminated with radiation of two different frequencies and the corresponding speckle patterns are compared to determine the magnitude and direction of shift from the first speckle pattern to the second. The magnitude and direction of the speckle pattern shift indicates the orientation of the object.Type: GrantFiled: February 7, 1997Date of Patent: September 22, 1998Assignee: Massachusetts Institute of TechnologyInventor: Lyle G.
