  • Patent number: 11630379
    Abstract: A scanning laser projection system includes a virtual protective housing circuit to automatically reduce accessible emissions of visible laser light by decimating areas of a projected image to reduce optical power exposure levels for safety, comfort, aesthetic, or system classification purposes. IR laser light pulses are scanned in a field of view, and a percentage of visible laser light pulses are blanked based on attributes of reflections of the IR laser light pulses.

  • Publication number: 20220390569
    Abstract: The embodiments described herein provide systems and methods that can improve performance in scanning laser devices. Specifically, the systems and methods utilize a non-uniform variation in optical expansion coupled with variation in the energy level of laser light pulses to provide an improved effective range over a scanning area. In general, the improved effective range varies over the scan field, with relatively long effective range in some areas of the scan field and relatively short effective range in other areas of the scan field. This varying range over the scan field is facilitated by expansion optics that provide a non-uniform variation in optical expansion for laser light pulses relative to position along a first axis in the scan field and by a light source controller that varies the energy level of the laser light pulses according to position along the first axis of the scan field.

  • Patent number: 11092679
    Abstract: Laser light pulses of at least two different wavelengths are reflected off a scanning mirror. A first time-of-flight distance measurement circuit receives reflected light pulses of a first wavelength and determines distances. A second time-of-flight distance measurement circuit receives reflected light pulses of a second wavelength and determines distances. The timing of transmission of laser light pulses of differing wavelengths are adjusted, and the data buffering of converted return pulses are adjusted, to compensate for laser light source misalignment.

  • Patent number: 4084890
    Abstract: A contact lens formed from a soft, flexible, hydrophilic, cross-linked polymeric material. The lens has a centrally located optical zone and an outer peripheral portion that has its maximum thickness intermediate the juncture of that portion with the optical zone and the thin edge of the lens.
