Abstract: (1167 Views)
Today, due to the widespread use of optical methods in the diagnosis and treatment of neurological diseases, it is very important to know the optical properties of nerve tissue and nerve cells. The use of light sources in these methods raises major challenges in how the beam propagates in the nerve fiber, which is a suitable substrate for neural signaling. Studies show that beam propagation is possible from both the axon and the myelin sheath. In this paper, according to the profile of nerve fiber refractive index and its similarity to fiber with a low refractive index core than the clad, the behavior of nerve fiber based on anti-resonant reflecting optical waveguide structure in different conditions are investigated. Light coupling to these two areas is shown by introducing axon and myelin sheath as a waveguide.
