  • Patent number: 10921188
    Abstract: A method for correcting a wavelength and a tuning range of a laser spectrometer in which the light from a wavelength-tunable laser diode, after being radiating through a gas, is detected and evaluated, wherein the laser diode is periodically driven with a current ramp, such that a time-resolved absorption spectrum of the gas is obtained upon the detection of the light, where in order to correct the wavelength and the tuning range of the laser spectrometer, a first step involves readjusting the central wavelength of the laser diode via the temperature thereof and based on the position of one of two different selected absorption lines in the detected absorption spectrum, and a second step involves correcting the tuning range of the laser diode via the gradient of the current ramp such that the spacing of the two absorption lines in the detected absorption spectrum remains constant.

  • Patent number: 10893829
    Abstract: A colorimetric optical sensor device includes a broadband light source configured to emit a light that is exposed to a fluid in a vessel. At least a portion of the light is reflected off of the fluid and received by an optical spectrometer. The optical spectrometer analyzes at least a portion of the received light to determine a main wavelength of the light. A controller correlates the main wavelength to a corresponding hematocrit or free hemoglobin concentration and generates an output indicative of the hematocrit or the free hemoglobin concentration of the fluid. The hematocrit or free hemoglobin concentration information may be used by a separation assembly in which the colorimetric optical sensor device may be incorporated to modify a separation procedure in which the monitored fluid is to be separated or is a component or constituent of a previously separated biological fluid.

  • Patent number: 10883940
    Abstract: A fluctuation-based fluorescence microscopy method, comprising influencing a point-spread function of the imaging of a sample emitting fluorescence radiation using an optical device in dependence on a parameter such that a point emitter is imaged into a representation with two image lobes. The relative positions of the lobes depend on the position of the point emitter relative to the focal plane. Synthetic pixels, smaller than detector pixels, are generated; for each synthetic pixel, pairs of pixel groups are defined among pixels of the detector based on the influencing of the point spread function. Each pair is assigned to an individual value of the parameter. In each frame and for each synthetic pixel, a signal correlation is ascertained and allocated as image brightness to the synthetic pixel for the parameter specification. Subframes for each frame are produced from the synthetic pixels, and a high-resolution sample image is produced from the subframes.

  • Patent number: 10871406
    Abstract: A self-delayed homodyne interferometer includes light source unit, a splitting unit, an interference signal acquisition unit, a scattered light intensity acquisition unit, and a signal processing unit. The light source unit generates probe light. The splitting unit splits into two branches, Brillouin backscattered light occurring in an optical fiber to be measured with the probe light. The acquisition unit receives scattered light of one branch, and uses a self-delayed homodyne interferometer to generate an interference signal. The acquisition unit receives scattered light of the other branch, and acquires intensity of the scattered light. The signal processing unit separates and acquires a frequency shift amount from the intensity of the interference signal, and strain and temperature change from the intensity of the scattered light. The acquisition unit can change a phase of the scattered light of the one of the two branches.
