Abstract: A data processing device includes: a storage device storing measurement data, including position information and velocity information about multiple measurement points in a space; and a processing circuit. The processing circuit acquires the measurement data from the storage device, recognizes measurement points on a stationary object from among the multiple measurement points on the basis of the velocity information, and generates point cloud data including the position information about the measurement points on a stationary object on the basis of a result of the recognition.

Abstract: An optical device includes a plurality of optical waveguides, and a planar optical waveguide. The plurality of optical waveguides each extend in a first direction, and are arranged in a second direction intersecting the first direction. The planar optical waveguide is connected directly or indirectly with the plurality of optical waveguides. The plurality of optical waveguides each allow light to propagate in the first direction. The planar optical waveguide includes a first mirror and a second mirror, and an optical waveguide layer. The first mirror and the second mirror face each other, and extend in the first direction and the second direction. The optical waveguide layer is located between the first mirror and the second mirror.

Abstract: An optical filter includes a filter array including filters two-dimensionally arrayed and a band-pass filter. The filters includes first and second filters. A transmission spectrum of each of the first and second filters has local maximum values of transmittance at three or more wavelengths included in a first wavelength region. The band-pass filter passes light in a second wavelength region including two or more wavelengths of the three or more wavelengths and not including one or more wavelengths of the three or more wavelengths. The filter array and the band-pass filter are disposed so that (a) the band-pass filter is located on an optical path of light that passes through the first and second filters or (b) the first and second filters are located on an optical path of light that passes through the band-pass filter.

Abstract: An optical device includes: a waveguide array including a plurality of waveguides; and a pulse generator. The waveguides are arranged in a first direction and extend in a second direction intersecting the first direction. The pulse generator inputs, as an input light beam, a light pulse of light to each of the waveguides. The light has a frequency spectrum in air with a maximum peak at a frequency corresponding to a wavelength λ, and the full width at half maximum of the maximum peak is Δν. The waveguides propagate the input light beams in the second direction and emit part of the input light beams as emission light. The pulse generator adjusts the difference in phase between input light beams to be inputted to two adjacent waveguides of the plurality of waveguides to thereby change a first direction component of an emission direction of the emission light.
