SCANNING ENDOSCOPE SYSTEM

摘要

A scanning endoscope system includes: a light-guiding section that guides illuminating light emitted from a light source; an optical scanning section that includes at least one pair of driving sections arranged at positions to face each other across the light-guiding section, and is capable of swinging the light-guiding section so that a position in an object illuminated by the illuminating light forms a trajectory according to a predetermined scanning pattern by driving the driving sections; and a drive signal outputting section configured to output a first drive signal which has a waveform with a predetermined positive voltage value as a center to one driving section in the at least one pair of driving sections which are arranged along a predetermined axial direction in the optical scanning section, and to output a second drive signal which has a waveform with a predetermined negative voltage value as a center to other driving section in the at least one pair of driving sections.
