Abstract:
1. A scanning endoscopic device which generates an image of a subject by scanning the subject, comprising: an optical fiber which is extended along a longitudinal axis, and which includes a proximal side fiber portion, and a distal side fiber portion placed to a distal direction side of the proximal side fiber portion, the optical fiber being configured to allow irradiation light guided from the proximal side fiber portion to the distal side fiber portion to exit from a distal end thereof; a lens optical system which is arranged in a state that the irradiation light exiting from the distal end of the optical fiber is collected on the subject; an actuator section which is placed to the distal direction side of the proximal fiber portion, and which is configured to drive the distal side fiber portion in a state that the distal end of the optical fiber moves on a substantially flat surface perpendicular to the longitudinal axis; an outer envelope tube which is provided to an outer peripheral direction side of the optical fiber; a light absorbing section which includes a black filling member filling a space between the proximal side fiber portion and the outer envelope tube in radial directions, and which is configured to absorb beam light having directivity in one direction; and a light scattering section which is provided between the proximal side fiber portion and the outer envelope tube in the radial directions, and which is configured to scatter the beam light.
