  • Patent number: 10969199
    Abstract: An optical system for providing crosswind aim point correction for a sniper rifles and similar weapons comprising an optical transmitter, an optical receiver, a display device and a processor. The optical transmitter produces a collimated laser beam for illuminating a spot on the target. The optical receiver receives optical signals transmitted by the optical transmitter and scattered back from the target and converts the optical signals into time varying electrical signals. The processor processes the time varying electrical signals to determine a path weighted average crosswind. The processor is equipped with software that permits it to calculate the path-weighted average crosswind utilizing at least three different methods.

  • Patent number: 10964221
    Abstract: An improved ground collision avoidance system and method is provided for aircraft driven during ground operations by electric taxi drive systems. One or more monitoring devices employing scanning LiDAR technology may be mounted in exterior locations on or near aircraft landing gears or aerodynamically in locations on the aircraft fuselage selected to generate panoramic three-dimensional images from any point of view within or without the aircraft as the aircraft is driven independently within an airport ramp area. The point of view images are transmitted in real time to displays in the aircraft cockpit and may be transmitted to displays outside and remote from the aircraft, allowing the pilot and airport personnel to monitor the aircraft moving within the ramp environment and to respond quickly to control the aircraft's electric taxi drive system-powered ground travel to avoid and prevent a potential collision.

  • Patent number: 10871445
    Abstract: A method and system for optical vortex transmissometry. The method uses optical orbital angular momentum (OAM) and optical vortices to discriminate coherent non-scattered light from incoherent scattered light. The system includes a laser which transmits a Gaussian laser beam through a medium. An OAM generating device is placed before a photodetector receiver. Coherent, non-scattered light passing through the OAM generating device forms an optical vortex, used to discriminate against the unwanted scattered signal that doesn't form a vortex. Alternatively, the system includes a transmitter which generates one or more OAM modes which are transmitted through a turbid medium. At the receiver, an OAM detection device analyzes the OAM mode spectrum of the received light. Coherent non-scattered light retains the OAM encoded at the transmitter, while scattered light does not. The attenuation of the channel is determined by comparison of the received OAM mode spectrum relative to the transmitted OAM mode spectrum.

    Abstract: A wearable device is configured with a one-dimensional depth sensor (e.g., a LIDAR system) that scans a physical environment, in which the wearable device and depth sensor generate a point cloud structure using scanned points of the physical environment to develop blueprints for a negative space of the environment. The negative space includes permanent structures (e.g., walls and floors), in which the blueprints distinguish permanent structures from temporary objects. The depth sensor is affixed in a static position on the wearable device and passively scans a room according to the gaze direction of the user. Over a period of days, weeks, months, or years the blueprint continues to supplement the point cloud structure and update points therein. Thus, as the user continues to navigate the physical environment, over time, the point cloud data structure develops an accurate blueprint of the environment.

  • Patent number: 10473784
    Abstract: A LiDAR system includes a signal generator for generating an output signal having a variable frequency. A modulation circuit receives the output signal from the signal generator and modulates the output signal to generate a pulsed modulation envelope signal configured to comprise a plurality of pulses, two or more of the plurality of pulses having two or more respective different frequencies. The modulation circuit applies the pulsed modulation envelope signal to an optical signal to generate a pulse-envelope-modulated optical signal comprising a plurality of pulses modulated by the pulsed modulation envelope signal. Optical transmission elements transmit the pulse-envelope-modulated optical signal into a region. Optical receiving elements receive reflected optical signals from the region. Receive signal processing circuitry receives the reflected optical signals and uses quadrature detection to process the reflected optical signals.

  • Patent number: 10473787
    Abstract: Systems and corresponding methods for use in measuring rotation characteristics (e.g., rotation magnitude and direction) of remote targets are provided. A laser light of a known frequency is incident upon the target and reflected. A portion of the reflected laser light is directed to detector field of view, where it is measured and analyzed. The detector field of view is divided into multiple segments, each capable of independently measuring the intensity of laser light incident thereon as a function of time. The linear rotation of the target may be determined from cross-correlation of the light intensity-time response measured at orthogonal pairs of detector halves arranged from combinations of the detector segments. The angular rotation of the target is further determined from this linear rotation.

  • Patent number: 10436885
    Abstract: A system calibrates one or more sensors mounted to an autonomous vehicle. From the one or more sensors, the system identifies a primary sensor and a secondary sensor. The system determines a reference angle for the primary sensor, and based on that reference angle for the primary sensor, a scan-start time representing a start of a scan and a scan-end time representing an end of a scan. The system receives, from the primary sensor, a primary set of scan data recorded from the scan-start time to the scan-end time. The system receives, from the secondary sensor, a secondary set of sensor data recorded from the scan-start time to the scan-end time. The system calibrates the primary and secondary sensors by determining a relative transform for transforming points between the first set of scan data and the second set of scan data.

  • Patent number: 10295328
    Abstract: A calibration method for improving distortion of a waveform of a point-spread-function without constantly executing feedback control to a wavelength-swept light source is provided. An interference signal is generated by varying voltage to be applied to a light source within one period, the interference signal is sampled at equal time intervals on a time axis, the point-spread-function is obtained through Fourier transform by multiplying by a first window function, and a complex analysis signal including frequency information of light is obtained through inverse Fourier transform by multiplying the point-spread-function by a second window function. After a variation in a frequency of the light relative to a time within one period is obtained at equal time intervals by unwrapping phase information of the complex analysis signal, a correspondence relationship between the variation in the frequency of the light within one period and a variation in voltage within one period is obtained.
