Abstract
<p>A coherent Raman rigid endoscopy system was developed for visualization of nerve. Recently, operation under the endoscope has become a standard operative method because of minimally invasive surgery, and nerve-sparing surgery has also been adopted to improve the quality of life of patients. Therefore, visualization of nerve under the endoscope is highly desired. Coherent anti-Stokes Raman scattering is employed to visualize myelinated nerve by the molecular vibrations of CH2 stretching of lipid, which is contained by myelin sheath. The developed endoscope, which has a tube with a diameter of 12 mm and a length of 270 mm, achieved 0.91% image distortion and 8.6% non-uniformity of CARS intensity in the whole field of view (650 μm diameter). CARS imaging of a rat sciatic nerve and nerves in fascia prostatae of Rabbit will be demonstrated. The imaging results of a new endoscope with 550 mm length will also demonstrated</p>
