<P>PROBLEM TO BE SOLVED: To solve a problem that when a light source and an imaging apparatus are adjacently arranged, the intensity level of light made incident on each portion in an imaging area of the imaging apparatus is made non-uniform and an image of high quality can not be acquired. <P>SOLUTION: A living body information acquisition device D1 for irradiating a living body portion with inspection light and receiving reflected light or transmitted light from the living body portion to pickup an image is provided with a light emitting part 4a for generating the inspection light, a light guide 3a for leading the inspection light generated in the light emitting part 4a from a light incident surface, guiding the inspection light and making the guided inspection light exit from a light exiting surface and an imaging part 1 for receiving the inspection light emitted from the light guide 3a and reflected by or transmitted through the living body portion and acquiring living body information. The inspection light made to exit from the light exiting surface of the light guide 3a has substantially fixed intensity along the longitudinal direction of the light exiting surface. <P>COPYRIGHT: (C)2008,JPO&INPIT |
