Özet
The laser nerve stimulation technique is an emerging stimulation method that utilizes some of the advantages of laser-tissue interaction. However, a narrow temperature range (41 °C – 48 °C) for successful, reliable, and safe laser nerve stimulation remains challenging for the method. This preliminary study investigates the depth-resolved thermal measurement performance of the system, comprising >22 MHz stretched-pulse mode-locked (SPML) laser and a 1505 nm laser for laser nerve stimulation. Providing the OCT signal in M mode, the system successfully measured the change in fringe amplitude as a function of temperature increases in a phantom model.
