Abstract:
An analyzer of a component in a sample fluid includes an optical source and an optical detector defining a beam path of a beam, wherein the optical source emits the beam and the optical detector measures the beam after partial absorption by the sample fluid, a fluid flow cell disposed on the beam path defining an interrogation region in the a fluid flow cell in which the optical beam interacts with the sample fluid and a reference fluid; and wherein the sample fluid and the reference fluid are in laminar flow, and a scanning system that scans the beam relative to the laminar flow within the fluid flow cell, wherein the scanning system scans the beam relative to both the sample fluid and the reference fluid.
Abstract:
Analyzers and analyzer systems that include an analyzer for determining multiple label species, methods of using the analyzer and analyzer systems to analyze samples, are disclosed herein. The analyzer includes one or more sources of electromagnetic radiation to provide electromagnetic radiation at wavelengths within the excitation bands of one or more fluorophore species to an interrogation space that is translated through the sample to detect the presence or absence of molecules of different target analytes. The analyzer may also include one or more detectors configured to detect electromagnetic radiation emitted from the one or more fluorophore species. The analyzer for determining multiple target molecule species provided herein is useful for diagnostics because the concentration of multiple species of target molecules may be determined in a single sample and with a single system.
Abstract:
A laser scanning microscope apparatus includes an irradiation unit (1) including an objective lens (13), a photodetector unit (3), an XY-scanning unit (12), and a Z-scanning unit (1, 2, 41). The irradiation unit (1) focuses a laser beam with the objective lens (13) to a specimen (6). The photodetector unit (3) detects light (L) generated from a position (S) irradiated with the laser beam. The XY-scanning unit (12) scans the laser beam in an X-direction perpendicular to an optical axis of the objective lens (13) and in a Y-direction perpendicular to the optical axis and the X-direction. The Z-scanning unit (1, 2, 41) scans the laser beam in a Z-direction parallel to the optical axis. When acquiring XY-two-dimensional image data by detecting the light (L) while scanning the irradiated position (S) in the X-direction and the Y-direction, the apparatus detects the light (L) while scanning the irradiated position (A) also in the Z-direction.

Abstract:
The present disclosure relates to a method and device for evaluating a wooden board with an elongated direction. Data indicating fiber orientation over the surface of the board is acquired and for a number of board sub-portions a nominal local modulus of elasticity, MOE, is determined based on the fiber orientation data and a nominal material parameter. A nominal global MOE in the elongated direction for the wooden board as a whole is generated and compared with a secondary global MOE. Based on the fiber orientation data and this comparison an estimated local modulus of elasticity, MOE, in said elongated direction is generated for a number of board sub-portions. This data may be used e.g. for reliable strength grading of wooden boards.
Abstract:
In a laser scanning method for measuring in vivo substances, wavelength of the anti-Stokes line is made greater than wavelength absorption band of the specific substance, the wavelength of the probe light is shifted from the wavelength of the anti-Stokes line by a shift amount of Raman scattering of the specific substance, and the wavelength of the Stokes light is shifted from the wavelength of the probe light by the shift amount of the Raman scattering of the specific substance. According to this, density (concentration and distribution) of lutein in an eye fundus is measured quantitatively and non-invasively from a signal strength level of the anti-Stokes line.1
