摘要
针对宽光谱光电系统多光轴平行性的工程化测试要求,设计一套光轴平行性测试的系统和方法。该系统采用离轴非球面折叠光路,设计出口径120 mm,焦距720 mm的平行光管,实现了轻量便携。采用模块化设计、多靶标集成技术,实现在同一光学系统里对红外、可见光、激光的光轴平行性测试。采用图像处理和自动控制技术实现多光轴平行性的定量检测,测量误差控制在0.1 mrad以内。经与CI测试系统对比测试,结果表明:光轴平行性测试一致性好,准确度高,具有工程化应用价值。
For the requirements of multi-axial parallelism measurement in engineering,a method and a system are proposed to test the multi-axial parallelism.This system adopts off-axis asphere two-double light route,and designs a collimator with aperture 120 mm and focus 720 mm,realizing light weight and portability.Modular design and multi-target integration are used to test the parallelism of infrared,visible and laser optical axis in the same system.Image processing and automatic control technology are used to realize quantitative measurement of multi-axial parallelism.The testing error is controlled within 0.1 mrad.Compared with the CI test system,the results show that the optical axis parallelism test has good consistency,high accuracy and engineering application value.
