    摘要： A wind speed prediction device (3) is formed, including a scattering signal acquiring unit (11) to acquire a scattering signal that is each of a plurality of beams after being emitted to space and scattered in the space, the beams having mutually different elevation angles, which are angles formed by a line-of-sight direction and a horizontal direction, a Doppler frequency calculating unit (12) to set a range bin width as distance resolution of each of scattering signals acquired by the scattering signal acquiring unit (11) in accordance with an elevation angle of each of the beams emitted to the space, and calculate a Doppler frequency of a range bin corresponding to a two-dimensional plane including an observation region from the each of the scattering signals, a first wind speed distribution estimating unit (13) to estimate a wind speed distribution in the two-dimensional plane from a plurality of Doppler frequencies calculated by the Doppler frequency calculating unit (12) using a VVP method, and a wind speed prediction unit (15) to predict a wind speed in the observation region from the wind speed distribution in the two-dimensional plane estimated by the first wind speed distribution estimating unit (13) using a two-dimensional Navier-Stokes equation.

    摘要： The present invention relates to a method for detecting aerosols using LiDAR(Light Detection and Ranging) technology. In particular, it relates to a method for detecting or analyzing aerosols suspended in the air, based on the mass concentrations of fine and coarse mode particles at different altitudes that are calculated using extinction coefficients as a function of distance for different wavelengths obtained from LiDAR measurements. The present invention method allows for detecting the total mass distribution as well as spatial distribution of aerosols according to their size.

    摘要： A multi-fiber optical sensor system (401, 402, 403, 404) includes a light source (675) configured to generate light energy, a transmitter fiber (130; 230; 330; 622) configured to receive the light energy from the light source and to project light energy out of a projecting end of the transmitter fiber over a transmitter fiber field of view (232; 432), and a plurality of receiver fibers (120, 121, 122, 123; 220, 221). Each of the plurality of receiver fibers has a receiving end aligned proximate and substantially parallel to the projecting end of the transmitter fiber and is configured to receive a received portion of the projected light energy reflected from a target within a receiver field of view (240, 241; 422, 424). The multi-fiber optical sensor system also includes a lenslet array (180; 280; 380) configured to shape the transmitter fiber field of view and give the transmitter field of view a finite cross-sectional area. The lenslet array has a plurality of lens (188, 190, 191, 192, 193) corresponding to the transmitter fiber and each of the plurality of receiver fibers and is further configured to shape the receiver fiber field of view, tilt the center of the field of view with respect to the axis of the projected light energy for each of the plurality of receiver fibers and give the receiver fiber field of view for each of the plurality of receiver fibers a finite cross-sectional area. The multi-fiber optical sensor system also includes a detector configured to detect the portion of the projected light energy received by each of the plurality of receiver fibers. The receiver fiber field of view for each of the plurality of receiver fibers crosses the transmitter fiber field of view between a first crossing point at a distance R min from a lens axis and a last crossing point at a distance R max from the lens axis. There is a center crossing point R mid at a point where a centerline of the receiver fiber field of view for each of the plurality of receiver fibers crosses a centerline of the transmitter fiber field of view. The range between R min and R max for each of the plurality of receiver fibers defines a detection zone (290, 291, 292, 293, 294, 295) such that each of the plurality of receiver fibers has a unique detection zone. Targets include a hard target and/or constituents of a cloud atmosphere.

    摘要： An optical ice detector and airspeed probe includes an ice detection module (40) and an airspeed module (42). The ice detection module detects the presence or absence of ice, water, or ice and water particles, and the airspeed module determines a line-of-sight speed along a directional vector, each based on backscatter light returns emitted from a common collimated light source. An electronics module (78) determines an airspeed of an aircraft based on the line-of-sight speed determined by the airspeed module and at least one aircraft parameter received from the air data system.
