Abstract: A scanning endoscope system includes an illumination fiber, an actuator section that has one or more pairs of drive sections, each pair being arranged at positions opposite to each other with the illumination fiber intervened in between, and a driver unit that outputs, to one drive section of the pair of drive sections arranged along a predetermined axial direction in the actuator section, a first drive signal having either a first waveform such that a minimum value of a voltage value, which varies periodically with a positive voltage value as a center, is not less than zero, or a second waveform such that a maximum value of a voltage value, which varies periodically with a negative voltage value as a center, is not more than zero, and configured to output, to the other drive section of the pair of drive sections, a second drive signal having the same waveform as the first drive signal and having a phase different from a phase of the first drive signal.

Abstract: A scanning endoscope system includes: a light guiding section that guides illuminating light from a light source; a light collecting section that collects the illuminating light to make the illuminating light exit toward an object; an optical scanning section that drives one or more pairs of driving sections disposed at symmetrical positions across the light guiding section, thereby swinging the light guiding section such that positions in the object illuminated by illuminating light from the light collecting section form a trajectory according to a predetermined scanning pattern; a drive signal output section that outputs a first drive signal to one driving section of a pair of driving sections disposed along a predetermined axis direction in the optical scanning section, outputs a second drive signal to another driving section, and sets a center voltage value of the first drive signal and the second drive signal to a voltage value different from 0 V.

Abstract: An endoscope system includes: an elongated insertion portion insertable into a body cavity of a subject; a first light source portion supplying illuminating light for illuminating an object in the body cavity of the subject; an illumination fiber guiding the illuminating light supplied from the first light source portion and emitting the illuminating light to the object from an emission-end-side end face; a light-receiving fiber group configured being provided with one or more optical fibers receiving, by incident-end-side end faces, return light of the illuminating light emitted to the object from the emission-end-side end face of the illumination fiber; and an optical unit capable of causing either the illuminating light supplied from the first light source portion or predetermined light different from the illuminating light, which is supplied from a second light source portion different from the first light source portion, to be incident on an emission-end-side end face of the light-receiving fiber group.
