Since thin or buried nerves are difficult to recognize with the naked eye, many cases have been reported leading to surgical side effects or complications. Therefore, in this paper, we propose a liquid crystal-polarized light imaging(LCPi) system with a simple structure that allows visualization of nerves during surgery. The LCPi system is designed to acquire polarization images of 0 and 90 degrees by time division and to identify the region having polarization characteristics through image processing. The validation of the system was accomplished by imaging around the sciatic nerve of the rat and visualizing nerves against the surrounding tissue. The LCPi system is expected to be used as an intraoperative nerve visualization system to minimize nerve damage after the optimization process.
