  • Patent number: 11656081
    Abstract: Novel small-footprint integrated photonics optical gyroscopes disclosed herein can provide ARW in the range of 0.05°/?Hr or below (e.g. as low as 0.02°/?Hr), which makes them comparable to fiber optic gyroscopes (FOGs) in terms of performance, at a much lower cost. The low bias stability value in the integrated photonics optical gyroscope corresponds to a low bias estimation error (in the range of 1.5°/Hr or even lower) that is crucial for safety-critical applications, such as calculating heading for autonomous vehicles, drones, aircrafts etc. The integrated photonics optical gyroscopes may be co-packaged with mechanical gyroscopes into a hybrid inertial measurement unit (IMU) to provide high-precision angular measurement for one or more axes.

  • Patent number: 11628510
    Abstract: A solder device includes a light source, a solder module, an optical guiding assembly, a sensor and a feedback controller. The light source emits waveband light guided to a to-be-soldered area for heating. The optical guiding assembly is disposed between the light source and the solder module, and the waveband light is guided to the solder module by the optical guiding assembly. The sensor is disposed on another side of the optical guiding assembly for receiving a sensing light beam and then generating a sensing signal. The sensing light beam is guided to the sensor by the optical guiding assembly. The feedback controller is connected with the sensor and the light source for receiving the sensing signal and then controlling the light source. The optical guiding assembly, the sensor and the feedback controller are integrated as a system controller. Therefore, the volume and weight of the solder module are compacted.

  • Patent number: 11588294
    Abstract: Disclosed is a system for arbitrary control of amplitude, phase and polarization characteristics of light in pulsed laser systems, allowing fast pulse-to-pulse modification of the above-mentioned parameters for single pulses or arbitrarily long and closely-spaced bursts of pulses. The control uses an electro-optic device, driving it by a specially designed high voltage driver. The operation of the driving electronics is based on the precise control of charging and discharging a Pockels cell inherent capacitance. This inherent capacitance is typically considered as parasitic. Therefore, prior voltage drivers operate in spite of the capacitance instead of using it. The present high voltage driver consists of a multitude of current-controlled stages capable of sinking and sourcing specific and adjustable currents into the capacitive load of the Pockels cell. The disclosed device and the corresponding control method allow for precise and energy-efficient shaping of Pockels cell control voltage.
