Patent number: 10551560Abstract: Arrays of tapered light-guides enable the development of snapshot multi-dimensional imaging systems, such as containing wavelength information in addition to spatial (x,y) image intensity-distribution information. As a result of the tapered guides, the input and output of the array can have the same overall dimension while producing greater total inter-guide free space at the output plane than present at the input plane for the introduction of optical elements, such as dispersers, as needed for particular applications. Individual guides may be tapered at different rates within the array and the array itself may be tapered as a whole.Type: GrantFiled: October 29, 2015Date of Patent: February 4, 2020Inventor: Tomasz S. Tkaczyk

Patent number: 9453763Abstract: A method of adjusting a resolution of a multidimensional imaging system includes taking a first hyperspectral snapshot by the multidimensional imaging system comprising a light processor comprising a plurality of optical fibers having a first end with an input spacing and a second end with an adjustable output spacing; adjusting the adjustable output spacing of the light processor to a new output spacing; and taking a second hyperspectral snapshot after adjusting the adjustable spacing of the multidimensional imagining system.Type: GrantFiled: November 21, 2014Date of Patent: September 27, 2016Assignee: William Marsh Rice UniversityInventor: Tomasz S. Tkaczyk

Patent number: 9243888Abstract: A method for imaging a sample. The method includes, during a single acquisition event, receiving depth-encoded electromagnetic (EM) fields from points on a sample that includes a first depth-encoded EM field for a first point and a second depth-encoded EM field for a second point, and redirecting the first depth-encoded EM field along a first predetermined direction to a first location on a dispersing re-imager and the second depthencoded EM field along a second pre-determined direction to a second location on the dispersing re-imager. The method further includes spectrally dispersing the first depthencoded EM field to obtain a first spectrum, re-imaging the first spectrum onto a first location on a detector, spectrally dispersing the second depth-encoded EM field to obtain a second spectrum, re-imaging the second spectrum onto a second location on the detector, and detecting the first re-imaged spectrum and the second re-imaged spectrum.Type: GrantFiled: November 30, 2011Date of Patent: January 26, 2016Assignee: William Marsh Rice UniversityInventors: Tomasz S. Tkaczyk, Mark Pierce

Patent number: 8654328Abstract: Devices and methods for hyperspectral and multispectral imaging are discussed. In particular, Image Mapping Spectrometer systems, methods of use, and methods of manufacture are presented. Generally, an image mapping spectrometer comprises an image mapping field unit, a spectral separation unit, and a selective imager. Image mapping spectrometers may be used in spectral imaging of optical samples. In some embodiments, the image mapping field unit of an image mapping spectrometer may be manufactured with surface shaped diamond tools.Type: GrantFiled: November 4, 2009Date of Patent: February 18, 2014Assignee: William Marsh Rice UniversityInventors: Tomasz S.
