  • Patent number: 11460346
    Abstract: The present disclosure provides a phase sensitivity calibration method based on a phase generated carrier (PGC) technology, which is characterized in that in the operation process of a PGC algorithm, an additional calibration signal with a phase of known magnitude is applied through a phase modulator. This signal is demodulated through an arctangent algorithm or a differential cross multiplication algorithm, and a demodulated output value corresponding to a unit phase in the algorithm is obtained. The phase of known magnitude can be obtained by converting a carrier modulation depth parameter according to a certain ratio.

  • Publication number: 20180039093
    Abstract: Head wear type automatic flip glasses include a housing, front automatic flipping lenses, rear fixing lenses, a transmission system, a circuit control system and a head fixing member. The front automatic flipping lenses are connected with the housing in a flipping way; the rear fixing lenses are in fixed connection with the housing. The front automatic flipping lenses are disposed in front of the rear fixing lenses. The transmission system and the circuit control system are configured in the housing. The head fixing member is located on the housing. The circuit control system controls the driving of the transmission system which is used for controlling the flipping of the front automatic flipping lenses. The head wear type automatic flip glasses are worn on the head to perform trainings. The front automatic flipping lenses flip automatically, so there is no need for hand-holding or manual flipping. That contributes to the integration of the flip training with reading and writing.

  • Patent number: 4814960
    Abstract: Micro-irregularities on a surface that interacts with (transmits or reflects) illumination from a light source are effective to control glare perceived by a viewer in the light path projected from the source, while maintaining effective energy and directionality of the projected light. Preferably the micro-irregularities are created by liquid dispersion comprising organic polymeric particles and allowing the coating to dry.

  • Patent number: 4734295
    Abstract: A method and kit for glare control and improvement of image transmission through a reflective-transmissive surface comprising surface irregularities to control glare. A dispersion of particles is applied to the surface and allowed to dry. Then an inert fluid coating is applied to the surface to enhance clarity. A liquid dispersion comprising a flattening agent is applied to the surface and allowed to dry so that the particles and flattening agent form a transparent glare-reducing coating. An inert fluid coating is applied to sufficient thickness to remove some, but not all, of the surface irregularities created by the glare reducing coating. A method of formulating the liquid dispersion is also disclosed.
