  • Patent number: 11051697
    Abstract: An apparatus for capturing a multispectral image of an object is described. The apparatus includes one or more means for transmitting a beam of laser light at a first wavelength and a beam of laser light at one or more additional wavelengths different from the first wavelength. There is a means for causing the beams of laser light to travel in a coaxial path and a moving mirror. The beams of light bounce off the mirror thereby producing a two dimensional projection pattern. This pattern travels from the mirror along a first path to an object and wherein some of the laser light penetrates the object and travels to an internal structure of the object. The reflection of the laser light returns to a photo detector along a path different from said first path.

  • Patent number: 11016019
    Abstract: A method and device for determining tensile force and adhesive force during the unwinding of a film from a roll without affecting the film, and which are usable at any radius of the spool and at any unwinding speed. The method and the device are based on determining the point where the film releases from the spool, and make use of the reflection of an ultrasonic wave. Emitted and reflected waves are radial at least when the emitted wave is incident upon the film which has not released from the spool. The method and device find applicability where tensile force, caused by the resistance of the roll to rotation, and also by adhesion of the film to the roll, must be determined. The method and device also find applicability where the adhesive force of the film to the roll must be determined.

  • Patent number: 10962478
    Abstract: An imaging system images a sample across one or more wavelengths. A light source illuminates a sample with one or more wavelengths of light, and an image sensor detects light from the illuminated sample. A linear variable long pass filter is positioned to filter light reflected from the sample to pass to the image sensor multiple different wavelength bands having different cut-off wavelengths. Wavelengths of light on one side of the cut-off wavelength are blocked and wavelengths of light on the other side of the cut-off wavelength are passed as multiple different long pass wavelength bands for detection by the image sensor. The image sensor detects light for each of the multiple different long pass wavelength bands from the sample. Data processing circuitry converts the detected light for the multiple different long pass wavelength bands for the sample into corresponding different long pass wavelength band data sets for the sample.

However, there is no standard supporting the acquisition and transmission of multi-dimensional information. It is interesting to obtain information related to a correspondence between pixels of a sensor of said optical acquisition system and an object space of said 10 optical acquisition system. Indeed, knowing which portion of the object space of an optical acquisition system a pixel belonging to the sensor of said optical acquisition system is sensing enables the improvement of signal processing operations. The notion of pixel beam, which represents a volume occupied by a set of rays of light in an object space of an optical system of a camera along with a compact format for storing such information is thus introduce.

  • Patent number: 10782459
    Abstract: Optical filter elements each include a parallelogram-shaped substrate with parallel light entrance and light exit surfaces and parallel slanted sidewalls slanted at an angle, and an interference filter disposed on one or both of the light entrance surface and the light exit surface. The optical filter elements are bonded together at the slanted sidewalls to form the optical filter array. Light is filtered by illuminating the optical filter array at an angle ? equal to or corresponding to the angle of the slanted sidewalls. In some embodiments the angle of the slanted sidewalls corresponds to the angle-of-incidence ? by Snell's law.

  • Patent number: 10774418
    Abstract: Systems and methods are disclosed for improving optical spectrum fidelity of an integrated computational element fabricated on a substrate. The integrated computational element is configured, upon completion, to process an optical spectrum representing a chemical constituent of a production fluid from a wellbore. The systems and methods measure in situ a thickness, a complex index of refraction, or both of a film formed during fabrication to generate a predicted optical spectrum. The predicted optical spectrum is compared to a target optical spectrum. Revisions to a design of the integrated computational element are conducted in situ to improve optical spectrum fidelity relative to the target optical spectrum. Other systems and methods are presented.

  • Patent number: 10775299
    Abstract: A Light Emitting Diode (LED) is added to a weed control system for calibrating the weed control system. A detector generates an electrical signal based on receiving light emitted by the LED. An electronically-tunable capacitor of a bandpass filter is adjusted based the signal received from the detector to adjust a center frequency of the bandpass filter so that light from an optical source, different from the LED, can more efficiently be detected by the weed control system.

    Abstract: An optical assembly is disclosed including two laterally variable bandpass optical filters stacked at a fixed distance from each other, so that the upstream filter functions as a spatial filter for the downstream filter. The lateral displacement may cause a suppression of the oblique beam when transmission passbands at impinging locations of the oblique beam onto the upstream and downstream filters do not overlap. A photodetector array may be disposed downstream of the downstream filter. The optical assembly may be coupled via a variety of optical conduits or optical fibers for spectroscopic measurements of a flowing sample.

  • Patent number: 10754165
    Abstract: An optical combiner that combines light from a plurality non-coherent light sources and directs it to a single output is described. The non-coherent light sources are arranged within a housing in a linear fashion, with light emitted from at least two of the non-coherent light sources directed towards a focusing lens by reflection from wavelength-selective mirrors, with the focus of the focusing lens directed to an input of an optical waveguide. Reflected light from at least one non-coherent light source passes through at least one wavelength-selective mirror that reflects light from a different non-coherent light source. A terminal non-coherent light source passes through all the wavelength-selective mirrors. Emitted light is transmitted or reflected along a plurality of optical axes that are parallel but offset to correct for refraction.

  • Patent number: 10690543
    Abstract: A system, method, and device for evaluating the intensity profile of a laser beam. The laser detection system has a target surface with an interior and an exterior. The target surface and a housing create a target pod with an enclosed interior chamber. A beacon is provided at the target pod to provide for targeting. A camera is provided that images the interior of the target surface from within the enclosed interior chamber. Some percentage of the intensity of the laser beam passes through the target surface uniformly and illuminates the interior of the target surface when the laser beam strikes the target surface. The illumination of and subsequent scattering from the interior of the target surface is imaged by the camera for analysis. By detecting the laser intensity as a function of position, the intensity profile of the laser beam can be quantified.
