Abstract: Provided is a high-speed and high-accuracy tablet spectroscopic measurement technology that enables total inspection. A pulsed light irradiation system irradiates a tablet being linearly moved by a movement mechanism with pulsed light in which an elapsed time in each pulse and a wavelength correspond to each other on a one-to-one basis, the output from a light receiver that has received transmission light from the tablet is input to a calculation means via an AD converter and an FPGA as an integration means, and a spectral transmission spectrum is calculated. In a case where the variation in spectral characteristic is measured, grouping is performed for multiple times of pulsed light irradiation performed on different locations, integration is separately performed, spectral transmission spectra are calculated and then compared.

Abstract: A light sheet imaging system, such as a light sheet microscope, comprises an illumination arrangement for generating a light sheet for three-photon excitation of a fluorescent sample, and a fluorescence collection arrangement for collecting fluorescence generated in the sample as a result of three-photon excitation by the light sheet. The light sheet may be a non-diffractive, propagation-invariant light sheet. The light sheet may be formed from and/or comprise a Bessel beam. A method of light sheet imaging comprises using a light sheet for three-photon excitation of a fluorescent sample, and collecting fluorescence generated in the sample as a result of three-photon excitation of the sample by the light sheet. Such a method may be used for light sheet microscopy.

Abstract: A method of directly measuring moisture content in an oil-filled transformer includes using an optical fiber that having a grating sensor, such as a Fiber Bragg grating, defined in the optical fiber. The various conductors (windings) in the transformer are insulated using an insulator such as paper and insulating oil is filled inside the transformer. Moisture in the transformer is absorbed by the paper that surrounds the windings. A moisture content at a specific location can be measured by placing the optical fiber with the grating sensor directly at the specific location to be measured. A physical parameter of the paper that absorbed moisture changes over time, causing a change in the grating sensor of the optical fiber which changes the spectral response of optical signals that are reflected by the grating sensor. The method provides an accurate method of measuring the moisture inside the transformer at the specific location.

Abstract: System and methods for analyzing single molecules and performing nucleic acid sequencing. An integrated device includes multiple pixels with sample wells configured to receive a sample, which when excited, emits radiation. The integrated device includes at least one waveguide configured to propagate excitation energy to the sample wells from a region of the integrated device configured to couple with an excitation energy source. A pixel may also include at least one element for directing the emission energy towards a sensor within the pixel. The system also includes an instrument that interfaces with the integrated device. The instrument may include an excitation energy source for providing excitation energy to the integrated device by coupling to an excitation energy coupling region of the integrated device. One of multiple markers distinguishable by temporal parameters of the emission energy may label the sample and configuration of the sensor within a pixel may allow for detection of a temporal parameter associated with the marker labeling the sample.
