Patent number: 11727294Abstract: A quantum information processing system comprises a light source, a detector, at least one spatial light modulator and at least one optical lens. The light source is configured to provide a beam of entangled photons. The at least one optical lens is configured to project the resultant beam onto the spatial light modulator, either by direct imaging or by performing a full or partial optical Fourier transform. Said spatial light modulator includes a plurality of discrete pixels and is configured to select one or more of the plurality of discrete pixels to generate a resultant beam from said beam of entangled photons. The resultant beam from said spatial light modulator is projected onto the detector. For optical computation, such as search algorithms, the configuration and projections are repeated to find the optimal solution.Type: GrantFiled: July 28, 2017Date of Patent: August 15, 2023Assignee: Trustees of Princeton UniversityInventors: Jason W. Fleischer, Chien-Hung Lu, Xiaohang Sun, Matthew Reichert, Hugo Defienne

Patent number: 10048201Abstract: A microscope is disclosed, the microscope having a light source defining an optical axis along a Z direction and a detector disposed in X-Y direction, orthogonal to the optical axis, the detector configured to capture images of an object. The microscope includes a fluid channel having an inlet and an outlet configured with a fluid flow to transport the object from the inlet to the outlet. The detector is configured to capture a plurality of images of the object as the object moves from the inlet to the outlet. The plurality of images of the object may have different heights of the sample with respect to the detector as the sample flows through the channel. The channel may be tilted with respect to the optical axis. The detector may be tilted with respect to the optical axis.Type: GrantFiled: September 10, 2013Date of Patent: August 14, 2018Assignee: THE TRUSTEES OF PRINCETON UNIVERSITYInventors: Jason W. Fleischer, Nicolas C. Pegard

Patent number: 9984450Abstract: A computer implemented method and apparatus for processing images comprises obtaining two or more images acquired by ultrasound. One or more operating parameters of the ultrasound probe (transducer) are varied so that the resulting images of a material or object under investigation differ with respect to intensity. Examples of parameters which may be varied include probe angle, frequencies, and even the time and/or resolution of the respective images. The method further comprises creating a new image by selectively subtracting one or more images from one or more others. In an embodiment, there are two images and one is partially subtracted from the other. If negative values are obtained as a result of the subtraction, such values are set to zero.Type: GrantFiled: December 2, 2015Date of Patent: May 29, 2018Assignee: The Trustees of Princeton University, Office of Technology and Trademark LicensingInventors: Jason W. Fleischer, Jen-Tang Lu

Patent number: 9628179Abstract: A system and method for filtering and enhancing signals from a noise background based on the nonlinear interaction of waves. The system and method amplify low-level signals, hide information in the signals, and then nonlinearly recover the signals. With the present invention, this can be performed for both spatial beams and temporal pulses. The signal self-filters and self-amplifies at the expense of the surrounding noise via the nonlinear medium.Type: GrantFiled: March 22, 2013Date of Patent: April 18, 2017Assignee: Princeton UniversityInventors: Jason W Fleischer, Dmitry V Dylov

Patent number: 8427650Abstract: Disclosed are systems and methods for characterizing a nonlinear propagation environment by numerically propagating a measured output waveform resulting from a known input waveform. The numerical propagation reconstructs the input waveform, and in the process, the nonlinear environment is characterized. In certain embodiments, knowledge of the characterized nonlinear environment facilitates determination of an unknown input based on a measured output. Similarly, knowledge of the characterized nonlinear environment also facilitates formation of a desired output based on a configurable input. In both situations, the input thus characterized and the output thus obtained include features that would normally be lost in linear propagations. Such features can include evanescent waves and peripheral waves, such that an image thus obtained are inherently wide-angle, farfield form of microscopy.Type: GrantFiled: December 2, 2009Date of Patent: April 23, 2013Assignee: Opteryx, LLCInventors: Jason W.
