Title:
SCANNING ENDOSCOPE
Document Type and Number:
WIPO Patent Application WO/2012/132750
Kind Code:
A1
Abstract:
Provided is a scanning endoscope (1) capable of obtaining images from a plurality of perspectives that enable stereoscopic observations while making the diameter of an insertion part small. The scanning endoscope (1) is provided with: an optical fiber (2), which is disposed inside a long and narrow insertion part (5), and which has two cores (21a, 22a) that project illuminating beams(L1, L2) at positions that are offset from each other in a direction that intersects the optical axes of the illuminating beams (L1, L2); a drive part (4) that performs two-dimensional scanning of the illuminating beams (L1, L2) by integrally vibrating the cores (21a, 22a) in a two-axis direction that intersects the long axis of the optical fiber (2); a light receiving part that receives return beams of the illuminating beams (L1, L2) together; a detection unit (8) that separately detects the return beams received by the light receiving part; and an image generation unit (9) that generates an image in the scanning region of each illuminating beam (L1, L2) from the return beams detected by the detection unit (8).
