摘要
描述了用 He- Ne激光的声光器件进行的声光调制和声光偏转实验 .调制曲线上有一个拐点 ,在拐点附近的一段曲线可看成直线 ,利用这段曲线进行调制可减少失真 .
An experiment of amplitude modulation and deflection of He-Ne laser beam by He-Ne laser acoustooptic device is described. A art of curve near inflection point on modulation curve can be considered as straight line, so it can be used to modulate laser beam to reduce distortion.
