A Photothermal Modelling Approach for Micro-LED Arrays in Wireless Optogenetics

Figure 8

The simulated irradiation of single micro-LED and micro-LED array in biological tissues: (a–d) the dispersion distribution of the light source of a single micro-LED when it is 1 mm-4 mm away from the target neuron; (e) the statistics of the dispersion of the light source of (a–d); (f–h) the dispersion distribution of the array of micro-LED when it is 0.1 mm-0.3 mm away from the target neuron. It can be seen that the farther the neuron, the more diffuse the light is and the weaker the light intensity is at the target neuron.
