抽象的。使用数字光处理技术在 4.62 μm 处演示了大角度、非机械光束控制。演示了 42 度的转向范围，但受到重准直透镜视场的限制。测得的轴上衍射效率为 8.1%，并且随转向角的 sin2 相关性而下降。然而，在42度转向范围内，动力变化小于25%。受控激光束的轮廓为高斯分布，发散度为 5.2 mrad。还演示了多波束、可随机寻址的波束控制。
Abstract. Large angle, nonmechanical beam steering is demonstrated at 4.62 μm using the digital light processing technology. A 42-deg steering range is demonstrated, limited by the field-of-view of the recollimating lens. The measured diffraction efficiency is 8.1% on-axis and falls-off with a sin2 dependence with the steering angle. However, within the 42-deg steering range, the power varied less than 25%. The profile of the steered laser beam is Gaussian with a divergence of 5.2 mrad. Multibeam, randomly addressable beam steering, is also demonstrated.
