<p>PROBLEM TO BE SOLVED: To provide an information acquisition device that enables an enlargement of a variable range of a wavelength of pulse light, and is high in usage efficiency of the pulse light to be used.SOLUTION: An information acquisition device acquiring information on a measured object comprises: a branch part that branches pulse light of a center wavelengthλc to be emitted from a light source part into a plurality of optical paths; a waveguide path that is provided in each of the plurality of optical paths; a multiplex part that multiplexes light to be emitted from a waveguide path provided in each of the plurality of optical paths; and an information acquisition part that detects light multiplexed by the multiplex part and with which an object is irradiated, and acquires information. The waveguide path provided in each of the plurality of optical paths is composed of a plurality of waveguide paths mutually different in a zero dispersion wavelength, and by the plurality of waveguide paths, a plurality of wavelength conversion light is generated that is different in a center wavelength from the pulse light of the center wavelengthλc.</p> |
