  • Patent number: 11940564
    Abstract: A laser radar device includes: a light source for outputting laser light; a scanner for causing the laser light to scan; a first optical system for receiving the laser light caused to scan by the scanner and incident on the first optical system and emitting the incident laser light in such a manner that a horizontal component of the incident laser light is different from a horizontal component of the laser light to be emitted; and a second optical system for receiving the laser light caused to scan by the scanner and incident on the second optical system and emitting the incident laser light in such a manner that an incident area of the incident laser light in the horizontal direction is the same as an incident area of the first optical system in the horizontal direction, and an emission area of the incident laser light is different from an emission area of the first optical system.

  • Patent number: 11933903
    Abstract: An optical transmission unit (3) transmits an optical signal having a light intensity set as a Low level component of a pulse. An optical partial reflector (6) is provided on a path through which transmission light is transmitted from a circulator (5) to the atmosphere, and reflects the optical signal. A detection unit (11) performs coherent detection on reception light using, as local light, a signal in a Low level section in the optical signal reflected by the optical partial reflector (6).

  • Publication number: 20240069190
    Abstract: A wind speed prediction device includes processing circuitry configured to acquire a scattering signal that is each of a plurality of beams after being emitted to space and scattered in the space; variably set a range bin width as distance resolution of each of the acquired scattering signals in accordance with an elevation angle of each of the beams emitted to the space, and calculate at least one Doppler frequency of at least one range bin corresponding to a two-dimensional plane including an observation region from the each of the scattering signals; estimate at least one wind speed distribution in the two-dimensional plane from the plurality of Doppler frequencies calculated; and predict a wind speed in the observation region from the at least one wind speed distribution in the two-dimensional plane using a two-dimensional Navier-Stokes equation.
