在OCT案例中,典型的应用是采用中心波长840nm的超辐射发光二极管。然而,1300nm的短波红外光,将在人体组织中有更好的穿透深度和较小的散射,因此将大幅提高短波红外相机的图像信号噪声比。 AO在长距离激光通信中的应用: 对地观测卫星成像传感器的分辨率不断增加,要求数据下行速率比目前可行的常规射频技术快的多。自由空间激光通信是一种很有前途的的技术,既不需要电线,也不需要光纤数据传输技术。然而,当远距离传送数据(>1公里),大气湍流会限制可传输的数据率。大气湍流造成光信号波前畸变随折射率变化。另外云彩会造成信号删减或链路阻塞。AO可以纠正激光脉冲的波前,从而实现的数据传输速率增加和改善比特错误率(BER)。尤其是“近地飞行终端”(飞机器下行),选择对于人眼安全的光波是地面站运营商的一个关键问题。自由空间激光的采用1550nm,比采用800 nm的光波对人眼安全提高一倍以上。这使得大功率激光器允许被使用。此外,1550 nm系统遭受的从宇宙空间来的背景光以及云与地球的反射光更少。同时,1550 nm的大气衰减是非常低的。
