由于光电测距仪具有测距精密、快速、准确和操作简便的优点,因此已广泛应用子距离测量,当它与经纬仪结合时便可同时观测角度。水利水电工程测量区域多为狭长地带,由于近代已发展了光电测距,目前较多地采用了光电测距导线来布设平面控制,并适宜于兼测三角高程。故本文简要介绍PC—1500电子计算器关于光电测
Because of the advantages of precision, fast, accurate and easy-to-use distance measurement, the photoelectric distance meter has been widely used sub-distance measurement, when it is combined with the theodolite can simultaneously observe the angle. Water conservancy and hydropower project measurement area mostly long and narrow strip, due to the modern development of photoelectric distance measurement, the current use of photoelectric distance measuring wire to lay the plane control, and is suitable for both trigonometric elevation. Therefore, this article briefly introduces the PC-1500 electronic calculator on photoelectric measurement
