Title:
OPTICAL SCANNING-TYPE OBSERVATION DEVICE AND OPTICAL SCANNING-TYPE OBSERVATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/182139
Kind Code:
A1
Abstract:
An optical scanning-type endoscope device (10) comprises: an illumination-use optical fiber (11); a driving unit (21) that drives the leading end of the illumination-use optical fiber (11) using a Lissajous　scanning pattern; illumination lenses (25a, 25b) that project the light emitted from the fiber leading end (11c) towards an observation subject (100); a light detector (35) that detects light obtained from the observation subject (100) as a result of light projection and converts such light to an electrical signal; an image processing unit (37) that generates an image on the basis of the electrical signal output by the light detector (35); and a phase adjusting unit that adjusts the phase of the driving waveform of the driving unit (21) so as to correct a phase shift between the driving waveform of the fiber leading end (11c) according to the driving unit (21) and the oscillation waveform of the fiber leading end.
