利用二维平面声表面波驱动器，研制了一种在两轴万向架上安装反射镜的转角超过20°的两轴光束转向样机。对于20度倾角的驱动，驱动功率输入需要10ms的持续时间，镜面结构的减振需要额外的10ms才能实现完全的角度保持。请注意，不需要使用任何电源来保持角度。由于执行器具有高分辨率，角度分辨率可达0.003度。波控样机显示了10/sup/4/动态范围的角度定位能力。
Steering angle over 20 degrees two-axis optical beam steering prototype that employs a mirror on a two-axis gimbal is developed, which takes advantage of two-dimensional planner surface acoustic wave actuator. For the actuation of 20 degrees of tilt angle, 10 ms duration of driving power input is required for actuation, then additional 10 ms for mirror structure's damping produced complete angle holding. Note that any power supply is unnecessary to hold the angle. The resolution of the angle was 0.003 degree because of high-resolution ability of the actuator. The beam steering prototype showed 10/sup 4/ dynamic range of angle positioning ability.
