Research on the Method of Detecting the Parallelism of Target Alignment of Pulse Laser Rangefinder

提出一种基于靶标调向装置的脉冲激光测距机光轴平行性检测方法。靶标十字分划中心分别与脉冲激光测距机白光瞄准光轴十字分划中心和激光发射光轴光斑中心对准,通过读取码盘数据计算光轴平行性误差。该方法操作简单,能够实时定量地检测光轴平行性误差,有效地提升了检测精度,实现了光轴平行性检测的数字化、自动化。

Proposed is an optical axis parallelism detection method for pulse laser range finder based on target alignment device.Target reticle center is aligned with the reticle center of visible light optic axis and laser optic axis respectively.Optic axis parallelism deviation is calculated with encoder data.The operation of this method is simple,and it can detect the error of optic axis parallelism in real time quantitatively.The detection accuracy of optical axis parallelism is improved effectively.Thus digital and automative detection is achieved.
