  • Patent number: 11061388
    Abstract: A scanner for image reconstruction of a structure of a target object uses a neural network trained to classify each segment of a sequence of segments of a modified wave into one or multiple classes. The sequence of segments corresponds to the sequence of layers of the target object, such that a segment of modified wave corresponds to a layer having the same index in the sequence of layers as an index of the segment in the sequence of segments. The scanner executes the neural network for each wave modified by penetration through the layers of the target object to produce the classes of segments of the modified waves. Next, the scanner selects the classes of segments of different modified waves corresponding to the same layer to produce an image of the layer of the target object with pixel values being functions of labels of the selected classes.

    Abstract: A method for sourcing plants includes performing nondestructive near-infrared (NIR) scans on selected plants, determining a predicted value of a characteristic for the selected plants based on evaluation of spectral data from the NIR scans against a characteristic model, and utilizing the predicted values for purchasing, processing, and/or financial forecasting. A method of sorting and processing plants includes determining a predicted value of a characteristic in gathered plants and determining a process to recover a primary product and/or a byproduct of the plants based on the predicted value. A method for forecasting includes determining a composite value of a characteristic in plants from a prior time period, correlating source data of plants to be gathered in the later time period with a predicted value of the characteristic in those plants, and determining a predicted composite value of the characteristic in the plants to be gathered in the later time period.

  • Patent number: 10969405
    Abstract: Methods and apparatus for performing chemical spectroscopy on samples from the scale of nanometers to millimeters or more with a multifunctional platform combining analytical and imaging techniques including atomic force microscopy, infrared spectroscopy, confocal microscopy, Raman spectroscopy and mass spectrometry. For infrared spectroscopy, a sample is illuminated with infrared light and the resulting sample distortion is read out with either a focused UV/visible light beam and/or AFM tip. Using the AFM tip or the UV/visible light beam it is possible to measure the IR absorption characteristics of a sample with spatial resolution ranging from around 1 ?m or less to the nanometer scale. The combination of both techniques provides a rapid and large area survey scan with the UV/visible light and a high resolution measurement with the AFM tip.

  • Patent number: 10627351
    Abstract: An inspection method for optical components that can be implemented to conform to performance specification MIL-PRF-13830 in order to grade surface imperfections, in particular scratches and digs. A dark-field microscope obtains a digital image of the component, and this digital image is processed to determine scratch and dig numbers. For scratches, the number is obtained by dividing the total intensity of the scratch by the scratch length. For digs, the number is obtained by determining dig diameter or by dividing the dig's total intensity by its area. According to our extensive testing, this automated digital image processing approach appears to faithfully mimic the subjective impression that a scratch makes on an expert inspector who is applying the visibility test of MIL-PRF-13830.

  • Patent number: 10557794
    Abstract: A system and method of non-intrusively measuring characteristics of a fluid in a substrate are provided. The fluid is located in a fluid channel in a substrate, and an electromagnetic radiation source emits an electromagnetic beam toward the fluid and the substrate such that a first part of the beam reflects off a first surface of the substrate and a second part of the beam travels through the fluid and reflects off a second surface of the substrate. A sensor detects the resulting interference pattern produced by the two parts of the beam. Changes in fringes of the interference pattern, such as shifting positions or intensities, relates to a change in the refractive index of the fluid. Since a change in refractive index relates to the density and pressure of the fluid, the changes in interference patterns can be used to discern changes in characteristics in the fluid such as pressure.

  • Patent number: 10430978
    Abstract: The present disclosure includes methods and systems for generating modified digital images utilizing a neural network that includes a rendering layer. In particular, the disclosed systems and methods can train a neural network to decompose an input digital image into intrinsic physical properties (e.g., such as material, illumination, and shape). Moreover, the systems and methods can substitute one of the intrinsic physical properties for a target property (e.g., a modified material, illumination, or shape). The systems and methods can utilize a rendering layer trained to synthesize a digital image to generate a modified digital image based on the target property and the remaining (unsubstituted) intrinsic physical properties. Systems and methods can increase the accuracy of modified digital images by generating modified digital images that realistically reflect a confluence of intrinsic physical properties of an input digital image and target (i.e., modified) properties.

  • Patent number: 10317774
    Abstract: Single-shot transient optical signals are recorded in a time regime of picoseconds to nanosecond. An auxiliary pump beam is crossed through the signal to sample a diagonal ‘slice’ of space-time, analogous to a rolling shutter. The slice is then imaged onto an ordinary camera, where the recorded spatial trace is a direct representation of the time content of the signal. The pump samples the signal by optically exciting carriers that modify the refractive index in a conventional semiconductor wafer. Through use of birefringent retarders surrounding the wafer, the integrating response of the rapidly excited but persistent carriers is differentiated by probing with two polarization-encoded time-staggered signal replicas that are recombined to interfere destructively.

  • Patent number: 10256594
    Abstract: A solid-state laser system may include first and second solid-state laser units, a wavelength conversion system, an optical shutter, and a controller. The first solid-state laser unit and the second solid-state laser unit may output first pulsed laser light with a first wavelength and second pulsed laser light with a second wavelength, respectively. The controller may perform first control and second control. The first control may cause the first and second pulsed laser light to enter the wavelength conversion system at a substantially coincidental timing, thereby causing the wavelength conversion system to output third pulsed laser light with a third wavelength converted from the first wavelength and the second wavelength, and the second control may prevent the first and second pulsed laser light from entering the wavelength conversion system at the coincidental timing, thereby preventing the wavelength conversion system from outputting the third pulsed laser light.
