  • Patent number: 10690817
    Abstract: An ultra-thin planar device is used for arbitrary waveform formation on a micrometer scale, regardless of the incident light's polarization. Patterned perforations are made in a 30 nm-thick metal film, creating discrete phase shifts and forming a desired wavefront of cross-polarized, scattered light. The signal-to-noise ratio of these devices is at least one order of magnitude higher than current metallic nano-antenna designs. The focal length of a lens built on such principle can also be adjusted by changing the wavelength of the incident light. All proposed embodiments can be embedded, for example, on a chip or at the end of an optical fiber.

  • Patent number: 10684221
    Abstract: With the method of the invention a wavelength-dependent refractive index of a specimen medium, which is examined with a light microscope, is determined. With the light microscope, a specimen measurement at the specimen medium which has an unknown refractive index is performed, wherein illumination light is radiated to the specimen medium and detection light coming from the specimen medium is measured. With the specimen measurement, a specimen measurement focus position of the illumination and/or detection light is measured. Using a mathematical model, in which a focus position of illumination and/or detection light is defined in dependence of a refractive index of a medium, the refractive index of the specimen medium is derived from the specimen measurement focus position. Furthermore, a light microscope for carrying out the method is described.

  • Patent number: 10573145
    Abstract: A fire detection and suppression system correcting fire detection based on wind. Wind may affect both the apparent position of the fire detected by the fire detectors and also the suppressant jet being delivered by a monitor. Typically wind results in shifting of estimated fire location away from the real fire in the direction of wind. Similarly the suppressant jet will also be diverted in the same direction. The system comprises fire detectors for acquiring two-dimensional fire location information for a fire. A wind sensor acquires wind information, often in region of the fire. A system controller then compensates the three-dimensional fire location information based on the wind information. Additionally, the position of fog/jet monitors is preferably compensated based on the wind information. The jet pressure setting is also ideally determined based on the wind.

  • Patent number: 10477173
    Abstract: A camera includes an optical filter for a sensor array of the camera. The optical filter includes a plurality of liquid crystal layers switchable between a reflection state and a transmission state. Each liquid crystal layer is configured to block spectral light in a different spectral light sub-band and transmit spectral light outside of the spectral light sub-band in the reflection state, and to transmit spectral light in the spectral light sub-band in the transmission state. An active illuminator of the camera is configured to emit active light in a selected spectral light sub-band. One or more of the plurality of liquid crystal layers is switched from the transmission state to the reflection state to tune the optical filter to block spectral light in all but the selected spectral light sub-band. The sensors of the sensor array are addressed to measure spectral light in the selected spectral light sub-band.

  • Patent number: 10458920
    Abstract: A fluid separation system is provided for separating a plasma-containing fluid into separated plasma and a concentrated fluid. The system cooperates with a fluid flow circuit including a fluid separation chamber and a plasma outlet line associated therewith for removing separated plasma from the fluid separation chamber. The system includes an optical sensor assembly that receives a portion of the plasma outlet line when the fluid flow circuit has been associated with the fluid separation system. To ensure proper installation of the plasma outlet line, the optical sensor assembly compares light received by its light detector to a baseline value, which is indicative of the amount of light received by the light detector before the plasma outlet line has been installed. The amount of received light being equal to or less than a selected percentage of the baseline value indicates that the plasma outlet line has been properly installed.

  • Patent number: 10429244
    Abstract: [Object] To obtain interference light having a stronger light intensity, and to more accurately measure a refractive index of a measured object, with a simplified configuration. [Solution Means] A light measurement device 100 includes a phase adjustment unit 120 and a detector 140. The phase adjustment unit 120 outputs reference light E(R) based on object light E1 being light to be obtained by transmission or reflection of light E from a light source with respect to a measured object 200, and signal light E(S) whose phase is adjusted to be different from a phase of signal light. The detector 140 derives a transmission or reflection light intensity distribution or a refractive index of the measured object 200, based on interference light E2 between signal light E(S) and reference light E(R) to be output by the phase adjustment unit 120. An optical axis of light E from a light source is linearly disposed.

  • Patent number: 10393648
    Abstract: A system for increasing light throughput in cavity enhanced spectrometry, and a model for cavity enhanced absorption measurements are presented. The cavity has an entrance mirror, an opposed exit mirror and a detector positioned adjacent the exit mirror. An input aperture is defined in the entrance mirror to allow light from a source to enter the cavity. The input aperture improves light throughput without significant departure from the theoretically predicted amplification of absorbance. This results in improvement of detection limits, even with mirrors of modest reflectivity and inexpensive detectors.
