摘要
目前激光测距技术仍处于需要进入跟踪状态才能获取距离信息的阶段,开展了动态扫描状态下激光测距技术可行性的研究。通过在警戒光路中加入反扫机构,并建立光路运动学模型,分析了警戒扫描状态下动态测距光路的误差,并对误差指标进行了分配。找到了反扫光路中对误差要求最严格的环节,为警戒扫描过程中的激光测距装置开发提供了技术基础与理论支撑。
At present,the laser ranging technology is still in the stage that it needs to enter the tracking state to obtain the distance information.Research on the feasibility of the laser ranging technology under the dynamic scanning state is carried out in this paper.By adding a reverse scanning mechanism to the light path and establishing a kinematic model of the light path,the error of the dynamic ranging light path under the scan state is analyzed,and the error index is assigned.The most stringent part in the reverse scanning optical path that needs the strictest control is found.It provides an important technical basis and theoretical support for the development of laser ranging devices in the alert scanning process.
