Long-range and high-performance total station ranging system

The invention discloses a long-range and high-performance total station ranging system which is characterized in that the output end of an optical system is connected with the input end of a signal amplification circuit, and the output end of the signal amplification circuit and the optical system are used for compressing laser for multiple times, so that energy is concentrated to generate parallel light beams; and the signal amplification circuit is used for amplifying the reflected laser signal. Integration of the system can be easily achieved, the anti-interference capacity of the system is improved, the full polarization maintaining optical fiber structure can keep the linear polarization state stability of light beams and the orthogonality of the polarization states of the two light beams, and displacement measurement errors caused by depolarization of linearly polarized light can be greatly avoided. 本发明公开了一种长测程和高性能全站仪测距系统，所述光学系统的输出端与所述信号放大电路的输入端连接，所述信号放大电路的输出端与所述光学系统用于对激光的的多次压缩从而使能量集中产生平行光束，所述信号放大电路对反射回
