| 摘要 |
In the present invention, an optical scanning-type endoscope device comprises: an illumination-use optical fiber (11) which guides light from a light source and the leading end of which is supported so as to be oscillatable; a piezoelectric substrate (28a) that is designed so as to cause the leading end of the illumination-use optical fiber (11) to oscillate in the Y direction; piezoelectric substrates (28b, 28d) that are designed so as to cause the leading end of the illumination-use optical fiber (11) to oscillate in the X direction; a piezoelectric substrate (28c) that drives the leading end of the illumination-use optical fiber (11) so as to at least partially cancel the Y direction oscillation component generated by the piezoelectric substrates (28b, 28d); an optical system that projects the light emitted from the illumination-use optical fiber (11) towards an observation subject; a light detection unit that detects light obtained from the observation subject and converts such light to an electrical signal; and an image processing unit that generates an image on the basis of the electrical signal output by the light detection unit. |
