摘要
光电测距仪是靠发光管发出的红外光来测定距离的，而以光管本身存在着相位不均匀性，因而使测量的距离存在着误差。本文对此误差用等值相位图描绘出来，从图中不仅能读出误差的大小，而且还能看出相位不均匀性的分布范围。
The infrared ray emitted by a shining tube is used to measure distance in a photoelectric distancemeter,but the ray phase is inconsistent, therefore, an error will be made.In this paper,the error is drown as an equal phase diagram or an isogram.From the isogram, not only can read the erroe numbers,but also see the distrabution range of the phase inconsistency. Simultaneously,it was discussed that how to correct the phase inconsistency.
