基于PLZT的高速光束偏转器是通过内部植入电极的棱镜来达到偏转光束的目的，用此方法可以实现快速大角度的光束偏转。

偏转角度：大于3度（电压：20V）
偏转频率： 小于25MHz.

The PLZT optical beam deflector is equipped with prism electrodes which steers optical beam at large angles at high frequencies. The deflector would be useful for optical switching, wide band tunable filter, image/data processing, and other applications.
Deflection angle> ±3 deg @20V
Deflection frequency < 25 MHz
