摘要
利用四象限光电探测器制成一种电子自准直仪，它具有自动测量，速度快，精度较高，能同时测量二维角位移的特点。文中介绍此种自准直仪的工作原理，以及检测和使用的情况。
A electronic auto-collimator is developed,in which a quadrant detector is used.This auto-collimator features automatic,high speed,high precision and two dimensional measurement of angular displacement. In this paper we present its working principle,calibration results,and an example of recording a shock process.
