Endoscopic image-guided laser treatment system based on fiber bundle laser steering. (a) Schematic illustration of optical setup. The figure was generated by the authors with Microsoft Power Point for Mac (v. 16.69.1)35. (b) The constructed setup. Red and green lines indicate optical path for laser irradiation and imaging, respectively. (c) Internal structure of the distal end. (d) External view of the distal end. LD, laser diode; LF, laser fiber; L1, L2, lens; P, pinhole; OL1, OL2, objective lens; M, mirror; GM, galvo mirror system; DM, dichroic mirror; FB, fiber bundle; GL, GRIN lens; C, CMOS camera; TL, tube lens.
