Patent number: 8873049Abstract: A low-cost optics, broadband, astigmatism-corrected practical spectrometer. An off-the-shelf cylindrical lens is used to remove astigmatism over the full bandwidth, providing better than 0.1 nm spectral resolution and more than 50% throughput over a bandwidth of 400 nm centered at 800 nm. The spectrometer includes a first spherical mirror disposed along an optical path in an off-axis (tilted) orientation; a diffraction grating disposed along the optical axis in a location optically downstream from the first mirror; a second spherical mirror disposed along the optical path in an off-axis orientation in a location optically downstream from the diffraction grating; a cylindrical optic disposed in the optical path; and a detector disposed in the optical path in a location optically downstream from the second spherical mirror.Type: GrantFiled: April 29, 2011Date of Patent: October 28, 2014Assignee: University of RochesterInventors: Jannick P.

Patent number: 8817270Abstract: An apparatus and associated method for testing a non-symmetric (e.g., phi-polynomial) surface. The apparatus uses several simple (singlet) optical elements (e.g., an Offner null configuration) and a tilted optic under test in combination with an active optical element (e.g., actuated, deformable membrane mirror, optical phase modulator, etc.) that together form a null or quasi-null that allows for conventional null-based interferometry. This solution solves the problem of exceeding the dynamic range of a conventional interferometer when trying to test non-symmetric optical surfaces.Type: GrantFiled: March 26, 2012Date of Patent: August 26, 2014Assignee: University of RochesterInventors: Jannick P.

Patent number: 8363225Abstract: A free-space Michelson Interferometer-based Dual Detection Frequency Domain-Optical Coherency Tomography (DD-FD-OCT) apparatus includes a non-polarizing beam splitter that can be used to misalign sample and reference beam paths to provide a stable ?/2 phase shift between simultaneously detected interfering sample and reference beams to eliminate the mirror image created by Fourier transformation during image reconstruction. A hybrid fiber system Mach Zehnder Interferometer- and free-space Michelson Interferometer-based Dual Detection Frequency Domain-Doppler Optical Coherency Tomography (DD-FD-DOCT) apparatus provides higher power efficiency and thus better sensitivity compared to the free-space DD-FD-OCT. Both DD-FD-OCT systems enable functional imaging with the contrasts of Doppler and that of polarization, in addition to full range images simultaneously.Type: GrantFiled: January 14, 2011Date of Patent: January 29, 2013Assignee: University of RochesterInventors: Jannick P.

Patent number: 7088457Abstract: Iterative algorithm methods and systems for slope or gradient-type data is presented for wavefront zonal estimation of regular and irregular pupil shapes. The methods and systems bears universal wavefront estimation matrices that are directly applicable to any pupil shape without the need to set up new matrices. The algorithm consists in first extending the sampling pupil to a larger regular square shape and second extrapolating the sampled slope data outside of the sampling pupil employing Gerchberg-type iterations. Unbiased least-squares wavefront estimation is then performed in the square domain. Results show that the RMS deviation error of the estimated wavefront from the original wavefront can be less than ?/150 after about twelve iterations and less than ?/100 (both for ? equal 632.8 nm) within as few as five iterations.Type: GrantFiled: June 10, 2004Date of Patent: August 8, 2006Assignee: University of Central Florida Research Foundation, Inc.Inventors: Weiyao Zou, Jannick P.

Patent number: 6774869Abstract: A teleportal system which provides remote communication between at least two users. A projective display and video capture system provides video images to the users. The video system obtains and transmits 3D images which are stereoscopic to remote users. The projective display unit provides an augmented reality environment to each user and allows users to view, unobstructed, the other local users, and view a local site in which they are located. A screen transmits to the user the images generated by the projective display via a retro-reflective fabric upon which images are projected and reflected back to the user's eyes.Type: GrantFiled: December 22, 2000Date of Patent: August 10, 2004Assignees: Board of Trustees operating Michigan State University, University of Central FloridaInventors: Frank Biocca, Jannick P.
