  • Patent number: 9234814
    Abstract: A reference surface is used to develop an empirical plot between a parameter of interest, such as roughness or modulation, and the position of the reference mirror in an interferometer by repeating measurements of the reference surface at different positions of the reference mirror so as to identify the in-focus position of the reference mirror. Serial quality-control measurements of samples of interest are carried out with the reference mirror in such in-focus position until a predetermined quality-control event triggers an automated system re-calibration by re-measuring the reference surface and, if the result does not correspond to the in-focus position of the reference mirror according to the plot, by finding a new in-focus position for the reference mirror using the same plot or, alternatively, a new similarly produced plot. Sample measurements are then resumed with the mirror placed at that new position.

  • Patent number: 9234817
    Abstract: Dust with various particle diameters entering a bypass passage, particularly, relatively large dust with a particle diameter of 100 to 200 ?m or so, is reliably caused to collide with a first step-shaped part, a second step-shaped part and a plate-like member to be sufficiently decelerated and reach a flow rate detecting device with low collision energy. This can prevent the flow rate detecting device from being damaged by collision of dust. Furthermore, the placement position of the plate-like member is optimized to suppress air turbulence at a flow rate detecting part, which achieves a good balance between flow rate detection accuracy and dust tolerance.

    Abstract: A portable spectrometer device includes an illumination source for directing at a sample, and a tapered light pipe (TLP) for capturing light interacting with the sample at a first focal ratio and for delivering the light at a second focal ratio lower than the first focal ratio. A linearly variable filter (LVF) separates the captured light into a spectrum of constituent wavelength signals; and a detector array, including a plurality of pixels, each of the plurality of pixels disposed to receive at least a portion of a plurality of the constituent wavelength signals provides a power reading for each constituent wavelength. Preferably, the TLP is lensed at one end, and recessed in a protective boot with stepped inner walls. The gap between the TLP and LVF is minimized to further enhance resolution and robustness.

  • Patent number: 9234842
    Abstract: The apparatus enables biometric authentication without the risk of forgery or the like and enables living-tissue discrimination. The roughness distribution pattern of deep-layer tissue of the skin covered with epidermal tissue is detected, thereby extracting a unique pattern of the living tissue. Biometric authentication is performed based upon the detected pattern. The roughness distribution pattern of the deep-layer tissue of the skin is optically detected using difference in optical properties between the epidermal tissue and the deep-layer tissue of the skin. Long-wavelength light, e.g., near-infrared light, is used as illumination light cast onto the skin tissue. A fork structure of a subcutaneous blood vessel is used as the portion which is to be detected, for example. The portion which is to be detected is determined based upon the structure of the fork structure. The living-tissue discrimination may be made using the subcutaneous blood vessel.

  • Patent number: 9234844
    Abstract: A chloride ion fluorescence detection method and device, and a use thereof. The chloride ion fluorescence detection method utilizes chloride ions to influence luminescence characteristics of some photoluminescent substances to change the emission spectrum of the photoluminescent substances. The concentration of the chloride ions is detected through two processes comprising the fiber surface film forming and test liquid preparation of a fluorescent reagent sensitive to the chloride ions and measurement of information of fluorescence peak wavelengths or intensities. The method can be applied to the online assessment of the corrosion environment of steel bar concrete or the measurement of chloride ions in a laboratory.

  • Patent number: 9234849
    Abstract: Methods (600) and systems (100) for inspecting an indirect bandgap semiconductor structure (140) are described. A light source (110) generates light (612) suitable for inducing photoluminescence in the indirect bandgap semiconductor structure (140). A short-pass filter unit (114) reduces long-wavelength light of the generated light above a specified emission peak. A collimator (112) collimates (616) the light. A large area of the indirect bandgap semiconductor structure (140) is substantially uniformly and simultaneously illuminated (618) with the collimated, short-pass filtered light. An image capture device (130) captures (620) images of photoluminescence simultaneously induced by the substantially uniform, simultaneous illumination incident across the large area for the indirect bandgap semiconductor structure.

  • Patent number: 9234852
    Abstract: The repeatability of strobe illumination for image exposure is improved over a wide dynamic range in a machine vision system wherein a relationship between a camera integration period and a pulse duration of a strobe light generator control the effective exposure of a camera image during a timing overlap between a beginning of the camera integration period and an end of the pulse duration. To avoid noise in the illumination, the illumination pulse duration may start, the camera integration period may begin after a delay relative to that start and not later than the end of the pulse duration, the pulse duration may end, and the camera integration period may end not earlier than the end of the pulse duration. The timing overlap may also be synchronized with a periodic ripple component in the strobe illumination, to provide improved repeatability.
