Publication number: 20240107162Abstract: A method for image enhancement includes capturing multiple input images of a scene, including at least a first input image having a first field of view (FOV) captured with a first focal depth and a second input image having a second FOV captured with a second focal depth. The input images in the sequence are preprocessed so as to align the images. The aligned images are processed in a neural network, which generates an output image having an extended depth of field encompassing at least the first and second focal depths.Type: ApplicationFiled: July 6, 2023Publication date: March 28, 2024Inventors: Dan C. Lelescu, Rohit Rajiv Ranade, Noah Bedard, Brian McCall, Kathrin Berkner Cieslicki, Michael W. Tao, Robert K. Molholm, Toke Jansen, Vladimir Krneta

Publication number: 20160049768Abstract: Embodiments of systems and methods are provided for a tunable laser device. The tunable laser device may include a diffraction grating connected to a pivot arm that pivots the diffraction grating about a pivot point to tune the laser device. In pivoting the diffraction grating about the pivot point, both the wavelength to which the diffraction grating is tuned and the length of the optical cavity may be changed. The length of the pivot arm may be selected to reduce the number of mode hops of the tunable laser device when tuning the laser device over its tuning range.Type: ApplicationFiled: August 3, 2015Publication date: February 18, 2016Inventors: Susan Hunter, Vladimir Krneta, Jason Ensher, Aaron Wegner

Patent number: 7495838Abstract: A laser system comprising a laser assembly for generating a light beam, and collimation assembly movable axially with respect to the laser assembly and being positioned in the optical path of the light beam. The collimation assembly comprises a collimation lens group comprising a first lens component positioned within a first lens mounting cell, a second lens component positioned within a second lens mounting cell and provided with a central portion for receiving and cooperating with the first cell to thereby adjust the axial spacing between the first and second lens components, means for radially adjusting the position of the second cell with respect to the first cell to thereby radially adjust the optical axis of the second lens component with respect to the optical axis of the first lens component, and means formed in the central and flange portions of the second cell for creating flexure therein.Type: GrantFiled: July 16, 2007Date of Patent: February 24, 2009Assignee: Inphase Technologies, Inc.Inventors: Vladimir Krneta, Kirk William Cook

Patent number: 7397571Abstract: Systems and methods are provided or use with a light source which generates a light beam. These systems may include a detector which detects light beam information and which determines whether multiple modes are present in the light beam so that the light source may be adjusted. These systems may further include a beam splitting device, such as an optical wedge, to provide two sample beams that intersect to provide a fringe pattern. The detector may then detect this fringe pattern and compute a visibility value that may be used to determine whether multiple modes are present.Type: GrantFiled: May 25, 2006Date of Patent: July 8, 2008Assignee: Inphase Technologies, Inc.Inventors: Vladimir Krneta, Larry Fabiny, Ian R. Redmond, Brian Riley, Aaron Wegner, Susan Hunter

Publication number: 20060279819Abstract: Systems and methods are provided or use with a light source which generates a light beam. These systems may include a detector which detects light beam information regarding a light beam exiting an etalon. The system then uses the detected information to determine whether multiple modes are present in the light beam so that the light source may be adjusted to return the light source to single mode operation.Type: ApplicationFiled: May 25, 2006Publication date: December 14, 2006Applicant: InPhase Technologies, Inc.Inventors: Vladimir Krneta, Larry Fabiny, Ian Redmond, Brian Riley, Aaron Wegner, Susan Hunter
