激光测距仪选用棱镜测量模式时,棱镜的装配位置是影响测距误差的主要因素,若用反射靶球代替棱镜,可以明显减小测距的误差。常见的靶球误差为0.1mm,仅用于中、低精度的测量,设计一种误差优于0.05mm的反射靶球,可用于高精度距离测量,且明显提高靶球互换性。一、关键技术的实现光线在角锥棱镜中反射时,其等效反射光路如图 Laser range finder prism measurement mode, the assembly position of the prism is the main factor affecting the range error, if the target instead of using the reflector prism, you can significantly reduce the error of ranging. Common target error of 0.1mm, only for medium and low precision measurements, the design of an error of better than 0.05mm reflective target ball can be used for high-precision distance measurement, and significantly improve the interchangeability of the target ball. First, the key technology to achieve Light reflected in the pyramid prism, the equivalent reflection of the optical path shown in Figure
