Publication number: 20170370823Abstract: The present invention discloses a method and system for conducting high temperature corrosion tests on metallic alloys without the need for extensive laboratory equipment and attendant safety measures through the use of a two-compartment ampoule where a vestibule connects these two compartments.

Any excursion from parallelism of the second beam path with respect to the first is rigorously independent of variation of the first laser beam path in yaw parallel to an underlying plane.Type: ApplicationFiled: January 10, 2017Publication date: December 28, 2017Inventors: Matthew A.

Publication number: 20170370842Abstract: The present invention provides a multi-channel fluorescence detecting system for detecting a plurality of fluorescence labeled analytes. The multi-channel fluorescence detecting system comprises a light source, a light filter device, a dual branch light guide tube, and a detector. The light source comprises a plurality of sub light sources for respectively providing an excitation light. The plurality of sub light sources are a plurality of single color Light emitting diodes (LEDs) which can be selectively turned on or off. The light source generates a plurality of lights with full width at half maximum (FWHM) wavelengths formed in a non-overlap manner. With the disposition of the plurality of sub light sources, the accuracy for detecting the specific analytes is raised, the light flux with a specific wavelength band is effectively raised (without raising the light flux of the full wavelength band), the structure is simplified, and the manufacturing cost is decreased.Type: ApplicationFiled: May 17, 2017Publication date: December 28, 2017Inventor: HUNG-JEN KAO

Publication number: 20170370843Abstract: The disclosed embodiments relate to a system that displays an image of the characteristics of the biological tissue. During operation, the system enables a user to illuminate a measurement location in an area of interest on the biological tissue by manipulating a point measurement probe, wherein the point measurement probe delivers both an excitation beam and an overlapping aiming beam that is visible to a camera. Next, the system obtains fluorescence information from a fluorescence signal emitted from the measurement location in response to the excitation beam. The system then captures an image of the area of interest using the camera and identifies a portion of the image that corresponds to the measurement location by identifying a location illuminated by the aiming beam. Finally, the system generates an overlay image by overlaying the fluorescence information onto the portion of the image that corresponds to the measurement location, and then displays the overlay image to a user.Type: ApplicationFiled: January 22, 2016Publication date: December 28, 2017Applicant: The Regents of the University of CaliforniaInventors: Laura Marcu, Dinglong Ma, Julien Bec, Dimitris Gorpas, Diego R.

Publication number: 20170370844Abstract: An image acquisition device includes a spatial light modulator modulating irradiation light, a control unit controlling a modulating pattern so that first and second light converging points are formed in an observation object, a light converging optical system converging the irradiation light, a scanning unit scanning positions of the first and second light converging points in the observation object in a scanning direction intersecting an optical axis of the light converging optical system, and a photodetector detecting first observation light generated from the first light converging point and second observation light generated from the second light converging point. The photodetector has a first detection area for detecting the first observation light and a second detection area for detecting the second observation light. The positions of the first and second light converging points are different from each other in a direction of the optical axis.Type: ApplicationFiled: January 12, 2016Publication date: December 28, 2017Applicant: HAMAMATSU PHOTONICS K.K.Inventors: Naoya MATSUMOTO, Koyo WATANABE

Publication number: 20170370845Abstract: A fluorescence detecting apparatus includes an excitation light applying section that applies excitation light to a protective film containing an absorbing agent. A photomultiplier tube detects fluorescence emitted from the absorbing agent due to absorption of the excitation light. A fluorescence passing filter removes light having wavelengths other than the wavelength of the fluorescence emitted from the absorbing agent, and a reflecting mirror having a reflecting surface reflects the fluorescence emitted from the protective film toward the photomultiplier tube. This reflecting surface is formed by a part of a curved surface forming a spheroid having first and second foci. The first focus is positioned at a target area of the protective film where the excitation light is applied, and the second focus is positioned at a light detecting element included in the photomultiplier tube.Type: ApplicationFiled: June 13, 2017Publication date: December 28, 2017Inventors: Yusaku Ito, Senichi Ryo, Junichi Kuki
