摘要

一种基于激光的能量和数据传输方案，用于视网膜外假体的完全无线操作。激光转向是通过一个单、双轴微机电系统反射镜和一个定制的弯曲反射光学来实现的，以使光束轨迹在瞳孔的不同角坐标上。在3D打印机器人眼平台上进行实时瞳孔检测和激光转向操作，并优化了最大的光功率输出。

Real-time Optical Beam Steering for Laser-Powered Epiretinal Prostheses

A laser-based power and data delivery scheme is described for completely wireless operation of a epiretinal prostheses. Laser steering is achieved using a single, two-axis microelectromechanical system mirror and a custom curved reflection optic are used to enable beam trajectories at different angular coordinates of the pupil. Real-time pupil detection and laser steering operation are characterized on a 3D printed robotic eye platform and optimized for maximum optical power delivery.
