Abstract: (3593 Views)
Laser light irradiation can be used for manipulating and controlling the neural cells. Light irradiation to the brain tissue can lead to temperature increase, which affect tissue function. The magnitude and spatial distribution of temperature variations are depended on tissue properties and light parameters. In this paper we study the interaction of laser with output power 1 mw at 470 nm which irradiated to tissue by two optical fibers. The fiber optics are multimode standard fiber and tapered tip fiber with diameters 200 µm and 10 µm, respectively. Simulation results show that the maximum temperature rise for multimode fiber and tapered tip fiber are 6×10-5 ͦC and 4.5×10-3 ͦC, respectively.
