<P>PROBLEM TO BE SOLVED: To facilitate position matching of a plurality of branched light and a plurality of optical fibers in photoacoustic imaging implemented by using the plurality of optical fibers and guiding laser beams. <P>SOLUTION: A photoacoustic imaging device 10 includes a light branching section 12 for respectively branching laser beams Lx and Ly into a plurality of branched beams Lxd and Lyd according to a prescribed pattern; a bundle fiber 14 including a plurality of optical fibers 13 in which one end surfaces 13e are arrayed while matching the branching pattern; and branched beam guiding sections 13x and 13y for guiding the plurality of branched beams Lxd and Lyd so that the plurality of branched beams Lxd and Lyd are incident to the cores 13a of the plurality of optical fibers 13 respectively from another end face 14e of the bundle fiber 14. <P>COPYRIGHT: (C)2012,JPO&INPIT |
