主要学术贡献：
（1）在偏振光学成像探测技术及其应用研究方面
带领团队开发研制了一款分孔径、共焦面、全偏振态同时探测型实时彩色偏振成像相机，该相机具有结构紧凑、通光量高、体积小、运算效率高等优点。所研制的偏振相机可用于移动目标、隐藏伪装目标及低对比度目标的实时跟踪与探测，亦可用于烟雾霾、薄云及浑浊水下环境中目标的超视距成像探测。提出了多种偏振透雾成像算法。该研究获得国家863计划和中科院“一三五”部署项目支持，荣获2016年度XX科学技术进步二等奖。
（2）在光纤受激布里渊散射（SBS）慢光时延技术研究方面
基于光纤双宽带光抽运方案，提出了构建特定谱型结构宽带SBS增益谱方法，获得了脉冲失真管理下的慢光信号脉冲的高保真传输；基于载频抑制和光纤光栅滤波特性，提出了一种单边带调制线性可控光学时间延迟方法；基于对泵浦光和斯托克斯光的偏振控制，提出了一种提高SBS慢光稳定性的方法；提出了一种多通道、大动态范围、连续可调的SBS慢光时间延迟线方案，获得了0-200 ns动态范围内连续可调的SBS慢光时延。
（3）在微纳光纤技术及应用研究方面
在微纳光纤/微光纤环谐振器/长周期光纤光栅的制作、性能及应用等方面，开展了一系列的研究工作。发现了多环串联结构微光纤结型环谐振器可产生宽线宽群时延，而多环并联结构微光纤结型环谐振器可产生窄线宽的群时延，为微纳光子器件实现宽平坦带宽的大群延时提供了一种新的途径；设计、制作并研究了多种高消光比、低损耗的基于光纤扭转的手性长周期光纤光栅(用于圆起偏器、液位传感和涡旋光产生)和基于光纤拉锥的长周期光纤光栅(用于应力、弯曲、液位、扭转、折射率传感）。
