  • THREE-DIMENSIONAL MEASUREMENT DEVICE
    Publication number: 20230366668
    Abstract: A three-dimensional measurement device includes: an optical system including an optical device that splits an incident light, irradiates a measurement object with a measurement light, irradiates a reference plane with a reference light, and combines at least part of the reflected measurement light with at least part of the reflected reference light to emit a combined light; a first light emitter that emits a first light that has a first wavelength; a second light emitter that emits a second light that has a second wavelength; a first imaging device that takes an image of an output light output from the optical device in which the first light enters; a second imaging device that takes an image of an output light output from the optical device in which the second light enters; and a control device that executes three-dimensional measurement of the measurement object.

  • System and method for rendering interactive aerial volumetric graphics and generating spatial audio using femtosecond lasers
    Patent number: 10228653
    Abstract: A plasma generator including: a femtosecond light source that generates a laser pulse beam; a processor that computes a computer generated hologram; a spatial light modulator that modifies the laser pulse beam in accordance with the computer generated hologram; a three dimensional scanner optically coupled to the spatial light modulator to direct the modified laser pulse beam to one or more focal points in air; and a lens that focuses the modified laser pulse beam. The modified laser pulse beam induces a light emission effect at a one or more focal points that can be visible, audible, and palpable.
