<p><P>PROBLEM TO BE SOLVED: To provide an optical scan type observation device for acquiring image information with brightness nonuniformity suppressed therein. <P>SOLUTION: The optical scan type observation device includes: a distal end 10a of an insertion part 10 for emitting laser beams from a light source 22 to a celomic inner wall S; an illumination fiber 11 for scanning the laser beams to be emitted from the distal end 10a of the insertion part 10 on the celomic inner wall S; a detection fiber 17 for receiving reflection light from the celomic inner wall S where the laser beams are scanned by the illumination fiber 11; a storage part 26 for storing intake efficiency information which indicates the distribution of intake efficiency of the reflection light to be taken in for each scan position by the detection fiber 17; and a light amount adjustment part 28 for adjusting the light amount of the laser beams thereby to allow the light amount of the laser beams so as to be proportional to the inverse number of a function of the intake efficiency with respect to the scan position, on the basis of the intake efficiency information stored in the storage part 26. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
