Patent number: 11959857Abstract: Provided is a Raman scattering measurement apparatus including a light source which emits light to smoke particles, a filter configured to block light which is incident to the smoke particles and passes through the particle and to allow Raman scattered light to pass therethrough, and a photodetector which detects the Raman scattered light passing through the filter in order to distinguish fire smoke generated due to a true fire from non-fire smoke generated due to daily life or industrial activity. The present invention also provides a fire determination apparatus including a unit which reads a Raman shift from Raman scattered light detected by the photodetector of the Raman scattering measurement apparatus, estimates a smoke component from the read Raman shift, and determines fire/non-fire from the estimated smoke component and a method thereof.Type: GrantFiled: September 17, 2021Date of Patent: April 16, 2024Assignee: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTEInventors: Hoe Sung Yang, Soo Cheol Kim, Hyun Seok Kim, Sang Hyun Mo, So Young Park, Kang Bok Lee, Kyu Won Han

Patent number: 11237370Abstract: A dual inclined beam line-scanning confocal microscope apparatus, associated method, and applications thereof. An embodied dual-inclined beam line-scanning confocal microscope (2iLS) utilizes dual, parallel excitation beams each having a focused line shape that are scanned over a fluorescent sample. The emitted fluorescence from the sample is spatially filtered and detected by an array detector. 2iLS microscopy provides high resolution, ultrasensitivity, and deep optical sectioning capability. A reduced excitation intensity lowers photobleaching and photodamage.Type: GrantFiled: April 30, 2019Date of Patent: February 1, 2022Assignee: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.Inventors: Kyu Young Han, Jialei Tang

Patent number: 11231570Abstract: A fluorescent emission HIST microscope utilizes a highly inclined tile beam that is scanned over a biological sample object. Fluorescence emission from the sample is propagated through a confocal slit into an sCMOS camera supporting a rolling shutter mode. The tile beam is synchronously swept with the readout of the camera to facilitate the rejection of background. The system provides for decoupling of the total imaging area from the beam thickness, which now solely depends on the width of the tile beam, enabling a thinner illumination and larger FOV imaging. Clear visualization of single molecules across a 130 ?m×130 ?m FOV provided a greater than 40× FOV than conventional HILO imaging. An associated imaging method is disclosed.Type: GrantFiled: April 30, 2019Date of Patent: January 25, 2022Assignee: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.Inventors: Kyu Young Han, Jialei Tang

Publication number: 20210325652Abstract: An illumination system may include an illumination source, a line-projection system to simultaneously illuminate a pupil plane with a static distribution of a plurality of one-dimensional (1D) coherent beams. Each of the 1D coherent beams of the plurality of 1D coherent beams may extend lengthwise along a coherent direction between boundaries of the pupil plane, have a width along an incoherent direction perpendicular to the coherent direction, and are distributed in a parallel distribution along the incoherent direction. Each of the 1D coherent beams of the plurality of 1D coherent beams is also spatially coherent along the coherent direction and spatially incoherent along the incoherent direction. The system may further include an objective lens to form a light sheet in an imaging plane based on an incoherent superposition of the plurality of 1D coherent beams.Type: ApplicationFiled: April 21, 2021Publication date: October 21, 2021Inventors: Jialei Tang, Vahid Ebrahimi, Kyu Young Han

Patent number: 9551658Abstract: In a STED fluorescence light microscope pulses of excitation light (3) are applied to a sample, which excite fluorescent entities contained in the sample for fluorescence, and which are focused on at least one focal area. Further, de-excitation light (12) is applied to the sample, which de-excites the excited fluorescent entities and which comprises an intensity zero point in the at least one focal area, as a continuous wave. Fluorescence light emitted by the excited fluorescent entities in the sample is registered after each pulse of the excitation light (3) and overlapping with applying the de-excitation light (13) with high temporal resolution between consecutive pulses of the excitation light (3).Type: GrantFiled: May 22, 2013Date of Patent: January 24, 2017Assignees: MAX-PLANCK-GESELLSCHAFT ZUR FOERDERUNG DER WISSENSCHAFTEN E.V., DEUTSCHES KREBSFORSCHUNGSZENTRUMInventors: Stefan W.
