【摘要】 陀螺仪是广义的导航控制领域内以惯性为原理基础的传感器,环激光陀螺仪则是以光学原理为基础的陀螺仪当中一个重要分支。小型激光陀螺是激光陀螺仪系列中体积最小的产品,具有较低成本、较低功耗、极小体积、极小重量等优点,是理想的小型战术惯性器件。在国内,小型激光陀螺的开发处于研制初期,对于激光谐振腔的装配采取人工手动操作,这对于小尺寸零件的装配有着天然的缺陷和瓶颈,而且无法通过操作经验和技巧的提升而解决。因此,实现自动化装配是小型激光陀螺制造技术的发展需求和重要方向。本文对小型激光谐振腔装配特点进行了剖析,搭建光学成像系统和CCD图像采集系统进行光学图像数字信号的获取。接着分析了光路系统定位精度和成像系统准确性,通过使用计算机LabVIEW软件进行数字图像处理和计算,降低干扰,突出特征,得到小型反射镜装配定位的中心。还搭建了电动多位置移动平台,利用计算机LabVIEW软件控制平台移动,带动小型反射镜对准小型腔体光学中心点进行定位装配。最后对具备功能的系统进行了调试和优化,解决故障、完善功能、提高性能。本文研制的基于图像处理的小型激光谐振腔装配系统,可以将反射镜精确地、自动化地装配到小型腔体的恰当位置上,提高了装配过程的洁净度和一致性,一定程度上解放了人工操作,提高了生产效率,为小型激光陀螺研制积累了经验。更多还原
