  • Patent number: 12360432
    Abstract: A non-linear optical crystal, such as a Lithium triborate (LiB3O5 or LBO) crystal, includes a first nanostructured optical surface including distributed pillars and gaps having random heights and cross sections to provide anti-reflection control and scatter control of first light incident on the first structured optical surface. The LBO crystal has an anti-reflective random structured optical surface formed by selective substitution of the surface species Boron-pentoxide (B3O5?) by Lithium Fluoride (LiF), resulting in a depletion layer with low reflectivity and low reflective scatter in the visible, ultraviolet (UV), and near infrared (IR) bands. The LBO crystal with the anti-reflective structured optical surface may be a monolithic structure and thus need not include a coating of an anti-reflective (AR) material, although the LBO crystal may include an optical surface coated by an AR material. The pillars and gaps may be randomly distributed or periodically distributed on the optical surface.

    Abstract: Embodiments of the present disclosure include techniques for forming nanotextured surfaces on various materials. In certain embodiments, a nanotextured surface of a wafer is formed in a processing chamber, such as a semiconductor processing chamber. A flat surface opposite the nanotextured surface is attached to a flat surface of a bulk material. In some embodiments the bulk material and the wafer are optical materials. In some embodiments, a second surface of the bulk material is also attached to a wafer having a nanotextured surface and a light may pass through the first nanotextured surface, the bulk optical material, and the second nanotextured surface with low reflection.

  • Patent number: 12057793
    Abstract: The present invention discloses an all-speed-range estimation method for a rotor position of a switched reluctance motor. Under a low-speed working condition, a sector is selected for triggering according to comparison between a current response value and a current threshold, so as to determine the rotor position of the motor; under a medium-speed working condition, the rotor position of the motor is determined, according to a change of the number of injected pulses with the motor speed, by querying a preset data table; under a high-speed working condition, a capacitor charging loop is designed since there is a small number of injected pulses; a response current formed by during injection of a pulse voltage charges a capacitor; the capacitor is detected to measure a voltage; and the rotor position is determined by querying a preset voltage-rotor position data table according to a voltage value.
