  • Patent number: 10952488
    Abstract: Sensor assisted head mounted displays for welding are disclosed. Disclosed example head mounted devices include an optical sensor, an augmented reality controller, a graphics processing unit, and a semi-transparent display. The optical sensor collects an image of a weld environment. The augmented reality controller determines a simulated object to be presented in a field of view, a position in the field of view, and a perspective of the simulated object in the field of view. The graphics processing unit renders the simulated object based on the perspective to represent the simulated object being present in the field of view and in the weld environment. The display presents the rendered simulated object within the field of view based on the position. At least a portion of the weld environment is observable through the display and the lens when the display is presenting the rendered simulated object.

  • Patent number: 10928311
    Abstract: A method and system for rapid, label free nanoscale chemical imaging and tomography (3D) with multiplexing for speed, and engineered coherent illumination and detection to achieve 3-D resolution at twice the Abbe limit. A sample undergoes photo-thermal heating using a modulated infrared light source and the resulting probe beam modulation is measured with one or more visible laser probes. Varying the infrared wavelength results in a spectrum which characterizes the chemical composition of the sample. Optionally, inelastically scattered light generated as a result of the probe beam interacting with the sample is collected simultaneously to yield additional chemical information.

  • Patent number: 10928317
    Abstract: An apparatus related method for measuring a property of a target material. The system may include a pump device that generates a pump beam. A modulation device may receive the pump beam and generate a modulated pump beam by modulating an intensity amplitude of the pump beam, which may be directed to the target material. A probe device may generate a probe beam, which is directed to the target material. A part of the probe beam may be reflected off of the target material, and has similar frequency characteristic as the modulated pump beam. A detection device may detect the reflected probe beam and produce a signal. An analyzing device may receive the signal and calculate the target material property by comparing the modulated frequency characteristics of the signal to those of the pump beam. At least one of the pump and the probe beams may be infrared light.

    Abstract: There is disclosed a system and method for measuring the polarization of light which utilizes a spatially-varying polarization beam. This measurement is analyzed and improved using novel imaging methods and image processing methods on a digital signal processing (DSP) system to determine the polarization of light. Various embodiments are described which can measure light polarization, determine polarizing material distributions, determine the optical rotary dispersion of samples, and determine the circular dichroism of samples. In certain embodiments, the binding constants and binding activity of molecular samples can be achieved. Given its reduced complexity and size, the system may be configured to be portable such that the system may be used in various applications outside of a lab setting.
