摘　　要：鉴于光电稳瞄系统的复杂性和科研开发的不可预见性,传统装调技术远不能满足产品科研设计发展的需求。着重分析探讨了光电稳瞄系统中各探测器光谱范围的差异性、光学平台结构的复杂性、光学轴系与回转轴系的一致性带来的精度难以实现的关键技术问题。通过多组自准直仪架设空间过渡基准,采用特定的大口径光轴调校装置,解决了光轴平行性调校问题。以调校光学轴系与机械回转系统的同步精度为出发点,确定了各部件之间的装配及装配误差的影响。通过设计的方位/俯仰天顶测量仪,解决了回转轴系正交性精度调校难题,实现了传统工艺方法和普通调校装置无法达到的设计指标和精度要求。The spectral difference between the sensors, complexity of optical bench mechanics, as well as alignment between the optical axes and revolving axes in stabilized electro-optical sight system make the system integration accuracy hard to achieve. The fine tuning for the optical axes boresight was achieved by setting a spatial transfer reference with several sets of autocollimators and adopting a large-aperture optical axis adjustment device. Based on the synchronous accuracy requirement of optical axes and mechanical revolving axes, the scheme to assemble various parts and the impact of the assembly errors on system accuracy were determined. With an azimuth/elevation zenith instrument designed for this work, the orthogonality accuracy of revolving axes was satisfactorily obtained. The design specification and accuracy achieved with this technology cannot be met by traditional technique or ordinary adjustment devices.
