  • Patent number: 11391622
    Abstract: An optical fiber sensing system with reduced spatial resolution and noise for multiple applications and method of operating same that employs a coherent receiver configured to detect and digitize both I and Q signals in two polarizations and performs signal beating in a digital signal processor (DSP) using the polarization-diverse signals to obtain beating results for multiple polarization state pairs that effectively reduces polarization induced fading effect(s) while providing faster sensing speed(s) and more efficient filtering. Since Rayleigh signals are captured in two orthogonal polarizations, four beating products are determined at once in the DSP and all are used for fiber strain determination thereby avoiding polarization fading.

  • Patent number: 10914685
    Abstract: A method of evaluating the integrity of a substrate used in medical device packaging include providing a flexible, porous substrate having a first major surface, and a second major surface, applying a UV absorbent layer over at least one of the first and second major surfaces of the substrate, and placing the substrate over a UV reflective surface. The method includes directing UV light toward the substrate and the UV reflective surface, whereby the UV absorbent layer absorbs light in a spectrum that matches the wavelength of the UV light, and detecting with a UV sensitive camera any UV light that is reflected from the first and second surfaces of the substrate. The substrate is rejected if the reflected UV light that is detected by the UV sensitive camera indicates that the substrate has at least one opening having a size that is greater than or equal to 10 microns.

  • Patent number: 10908072
    Abstract: Systems, methods, and computer-readable storage media are disclosed for providing a structured total internal reflection fluorescence (sTIRF) imaging system providing improved out of focus blur rejection and improved image contrast. The sTIRF imaging system may be configured to illuminate a sample using two beams of light (e.g., a primary beam of light and an interfering beam of light). The interfering beam of light may be configured to create interference with respect to the primary beam of light. The sTIRF imaging system may be configured to capture a plurality of intermediate images of the sample during the illuminating, and to generate a final image of the sample based on the plurality of intermediate images. The interference caused by the two beams of light may enable the sTIRF imaging system to reject out of focus blur based on detection of whether fluorescence emissions from the sample being imaged fluctuate or remain static.

  • Patent number: 10895504
    Abstract: A measurement auxiliary member is placed on an arrangement surface of a prism. A measurement object is placed on an upper surface of the measurement auxiliary member. The measurement auxiliary member totally reflects the terahertz wave input from a lower surface by the upper surface and outputs the totally-reflected terahertz wave from the lower surface. A main pulse of a terahertz wave totally reflected by the upper surface of the measurement auxiliary member without multiply-reflected inside any optical element on an optical path of the terahertz wave, and a noise pulse of a terahertz wave multiply-reflected inside any optical element on the optical path and reflected on an interface between the prism and the measurement auxiliary member, are temporally separated from each other when detecting a correlation by a terahertz wave detection element.

  • Patent number: 10859493
    Abstract: An SPR detection apparatus has an optical system with a sensor member including a planar metallic layer, the sensor member being removably mountable to a housing. First optics direct an incident beam toward a rear side of the metallic layer at a predetermined range of angles to a normal to the sensor layer. Second optics guide at least one reflected beam, corresponding to the incident beam, from the metallic layer to the transducer. The transducer converts incoming electromagnetic radiation to an electrical signal for transmission to a signal processor disposed in the housing and operatively connected to the at least one opto-electrical transducer so as to detect a surface plasmon resonance angle. The first optics are configured so that the at least one incident beam spans at least about 20°.

  • Patent number: 10816466
    Abstract: An analysing apparatus comprises a fluid container defining a sample chamber. A sensor having a transparent body with a nanostructured surface is coupled to the fluid container such that the nanostructured surface is exposed to the sample chamber. An excitation and detection apparatus directs a beam of incident polarised electromagnetic radiation onto the reverse face of the body at the Brewster angle, causing no or substantially no reflection of the polarised radiation from the reverse face. The beam of reflected radiation emerges from the reverse face after reflection from the nanostructured surface. The apparatus is simpler and cheaper in comparison with known alternatives that use ATR prisms to create ATR of the light to excite a planar surface.
