Claims (10)

  1. An optical device for displaying information on a road surface,
    A light emitting unit that emits coherent light; and an irradiation unit that includes a diffusion unit that diffuses the coherent light emitted from the light emitting unit to irradiate an irradiation region of a predetermined shape;
    A control unit for controlling the irradiation unit;
    A scanning unit for entering light from the light emitting unit at a predetermined position on an incident surface of the diffusion unit;
    With
    The diffusion unit includes a first diffusion element region including a set of element diffusion elements in which predetermined predetermined information is recorded, and a first diffusion element group including a set of element diffusion elements in which information different from the first diffusion element region is recorded. A diffusion element divided into at least two diffusion element regions;
    A different wavefront is formed from each point of the exit surface of the element diffusing element, and is overlapped independently in a corresponding irradiated region .
  2. The information is a character or an image
    The optical apparatus according to claim 1.
  3. The information is an arrow
    The optical device according to claim 1, wherein the optical device is an optical device.
  4. A storage unit for storing a correspondence relationship between the first irradiated region corresponding to the first diffusion element region and the second irradiated region corresponding to the second diffusion element region;
    The control unit drives the scanning unit based on the correspondence relationship stored in the storage unit.
    The optical device according to any one of claims 1 to 3, wherein
  5. A detection unit that detects the state of the moving body in the traveling direction,
    The control unit emits light to the irradiating unit based on the correspondence stored in the storage unit so as to guide the moving unit to a predetermined position when the detection unit detects the moving unit. Irradiate
    The optical apparatus according to claim 4.
  6. The information allows the observer to recognize the traveling direction of the moving body
    The optical apparatus according to claim 5.
  7. The information is a line extending from the moving body in the traveling direction.
    The optical device according to claim 5, wherein the optical device is an optical device.
  8. An optical device according to any one of claims 1 to 7 is mounted.
    A moving object characterized by that.
  9. An optical device according to any one of claims 1 to 7 is mounted.
    A vehicle characterized by that.
  10. A method for controlling an optical device according to any one of claims 1 to 4,
    The optical device includes a detection unit that detects a traveling direction of the moving body,
    Determining whether the detection unit senses the moving body; and
    When the detection unit senses the moving body, the irradiation unit irradiates the information to the irradiation region;
    The operation count of the optical device is started, and when a predetermined time has elapsed, the process returns to the step of determining whether or not the detection unit has sensed the moving body.
    A control method for an optical device.
