Patent number: 11506612Abstract: A system and method for detecting pathogenetic analytes including exciting a large target input area with radiation to produce scattered light to form an input beam, reformatting, with an optical slicer system, the input beam to produce an output beam, dispersing the output beam to produce an output area, capturing excitation data from the output area; and determining, with a processor, a presence of a particular analyte in the input area based on the excitation data. The input area can be greater than 100 micron squared and less than one million microns squared. The optical slicer system can be a high throughput virtual slit system. SERS analysis detects analytes of interest with both high resolution and sensitivity simultaneously, and is applicable for detection of the presence of viruses.Type: GrantFiled: July 29, 2021Date of Patent: November 22, 2022Assignee: TH Bioventures, LLCInventors: Leif E. Honda, Phil A Cestaro, Jon C Wetzel, Songhao Li, Arsen Hajian, Ronald J Sostek

Patent number: 9574941Abstract: A spectrometer is provided, the spectrometer having an interferometer generating an interferogram by splitting an interferometer input signal between a reference arm and a variable delay arm, and introducing a delay between the split interferometer input signals prior to interfering the split interferometer input signals. The spectrometer additionally has a controllable delay element operable to adjust the delay introduced by the interferometer and a dispersive element outputting a plurality of narrowband outputs representative of a received broadband input signal. The interferometer and dispersive element are optically connected to output a plurality of narrowband interferograms representative of a spectra of a spectrometer input signal received by the spectrometer, and the plurality of narrowband interferograms are received by a detector array for analysis.Type: GrantFiled: May 30, 2012Date of Patent: February 21, 2017Assignee: TORNADO SPECTRAL SYSTEMS, INC.Inventors: Arthur Nitkowski, Arsen Hajian

Publication number: 20130286404Abstract: Methods and apparatus are provided for the alignment of an interferometric system. A spatial filter comprising a reflective pinhole is provided at the output of the interferometer, and tilt is measured by a tilt detection subsystem positioned to reimage the pinhole. A shear detection subsystem is positioned to image an offset of the interferometer beams. Tilt and shear offsets are determined by comparing measurements obtained from the tilt and shear subsystems with pre-recorded measurements obtained for an aligned state. The tilt and shear offsets are employed to realign the system using positioning controls corresponding a reduced number of dominant degrees of freedom of the system.Type: ApplicationFiled: November 16, 2011Publication date: October 31, 2013Applicant: THUNDER BAY REGIONAL RESEARCH INSTITUTEInventors: Andrew Cenko, Arsen Hajian, Jeff Meade
