摘要
在分析光栅传感器原理的基础上,针对测量高压线缆时要求测距仪精度极高的问题,提出将高精度光栅传感器应用于激光测距仪的方案,在激光测距仪平台设计中安装两个光栅传感器,分别输出仰俯角和水平转角,并利用细分算法设计了光栅传感器的细分电路,大大提高了测量精度。
This paper introduces laser ambulator simply, on the basis of analysis the principle and classes of grating sensor, in view of the problem that ambulator requires high precision when surveying the high voltage cable, a scheme of using grating sensor in laser ambulator is proposed. Two diffraction gratings sensors in the laser ambulator platform design are installed, which separately output elevation angle and the agimuth angle, and the subdivision circuit of grating sensor is designed using subdivision algorithm, increasing the measurement precision greatly.
