摘要

在传输和紧凑型设备中实现大孔径光束控制一直是包括激光雷达和3D显示在内的各种技术的重要设计目标。提出了一种利用电润湿棱镜阵列的孔径可变光束导向方法。通过单独控制电极的电压,可以同时控制光束转向和成形,从而使三维光束转向成为可能。棱镜阵列的总孔径可以根据阵列的数量而变化。运行速度为25ms,横向和纵向转向范围为±9.5°,对角线方向为±13.2°。光功率范围为- 47.6D ~ 47.6D。光学特性的测量,如RMS波前误差的总和,棱镜的所有像差和曲率半径,即界面的平面度,并演示了一个三维光束导向。

Beam steering and forming in compact electrowetting prism array with separate electrode control
Large aperture beam steering in a transmissive and compact device has been an important design objective for various technologies including LIDAR and 3D displays. We propose a new aperture variable beam steering method using an electrowetting prism array. By individually controlling the voltage of electrode, 3-dimensional beam steering is possible because it can manipulate beam steering and forming simultaneously. The total aperture of the prism array can be varied depending on the number of arrays. The operating speed was 25ms and the steering range was ±9.5° in the transverse and longitudinal directions, and ±13.2° in the diagonal direction. The range of optical power was −47.6D to 47.6D. Measurement of optical properties such as the RMS wavefront error as the sum of all aberrations of the prism and the radius of curvature, which is the flatness of the interface, and a demonstration of a 3-dimensional beam steering is also presented.
