入射激光光轴检测分辨率主要由固有分辨率和细分精度两部分组成,但大气信道二次调制会直接引入误差进而影响光轴检测的检测精度。为了降低光轴检测系统对大气信道环境的敏感程度,首先CCD光轴检测系统和四象限(4QD)光轴检测系统作为两种典型的光轴检测系统其检测模型被分析,并推导在大气环境中其分辨率、固有分辨率、细分精度与光斑尺寸之间的关系。接着以4QD检测模型为例,指出信标光的信噪比和光轴偏移量是影响光轴检测系统的重要技术参数。最后通过一个野外光轴对准试验验证了光轴细分精度对大气干扰敏感,而固有分辨率受大气影响不大,可以改变光斑尺寸来改善光轴检测系统对大气干扰的敏感程度。

采用分步傅里叶法理论探究了有限能量艾里光束和非线性加速光束在有偏压光伏光折变介质中的交互效应。结果表明:调节光束初始间隔和入射角度可使同相位或反相位有限能量艾里光束相互吸引或排斥。同相位时不仅产生呼吸孤子和孤子对,在适当参数条件下还可形成分叉孤子;反相位时仅有孤子对产生;同相位非线性切趾加速光束交互可以产生奇数个呼吸孤子,反相位非线性切趾加速光束交互可以产生偶数个呼吸孤子对。此外,呼吸孤子的峰值强度、呼吸周期和相互作用力的大小均可以通过外部偏压和入射角度进行有效调控。研究结果可为艾里光束交互调控提供理论基础,同时在全光信息处理和光学网络器件制备等领域具有潜在的应用前景。
