公司介绍
美国Brimrose公司是一家极富创新性的全球关注的高科技公司，主要致力于声光技术和先进材料的研发。声光可调谐滤波器近红外(AOTF-NIR)技术是Brimrose的核心技术，具有扫描速度快而且不受外界环境如温度、湿度、灰尘等影响，非常适合在线质量控制和现场品质检测。
技术说明
Brimrose的光纤耦合声光移频器系统用于各种光信号的频率偏移。基于多普勒频移，声光调制器或声光频移器中的衍射一阶光束的频率以某种被载波频率（波长）移到频率（波长）中。如果入射声波沿着入射光波的方向入射，激光频率就向高侧移动。如果入射声波在入射光波的相反方向上引入，激光就向低频侧移动。
一个fiber-coupled AOFS典型的3 dB的光谱范围是~60-120 nm，3dB的频率范围是中心频率的~10%。对于宽带应用（可调范围移频），Brimrose开发设计的 AOFS当期已经可以实现可扩展频率的范围高达100 MHz。
