利用反射式光学系统对激光指示器的光轴进行了调校。提出了激光指示器及观瞄装置的光轴校正方案，并建立了调校装置。该装置由离轴抛物面反射镜、十字靶标、背景光源、图像采集装置及其它附件组成。对调校装置的测量精度进行了标定和计算。结果表明，该装置的测量精度可达到0．05mrad。利用该装置对激光指示器的光轴进行了调校，并给出了系统示意图和测试效果。

The rectifying technology of the optical axis of the laser ranger director is introduced with reflecting optical system. The rectifying designing of the optical axis of the laser ranger director and sighting devices are given,and the rectifying device is set up. The system is composed of off-axle paraboloid reflector,cross line target,background light,imaging collecting system and other devices. The rectifying device is calibrated,the rectifying precision of the rectifying device is calculated. The result shows that the accuracy limit reaches 0.05mrad. The rectifying of the laser ranger director is carried out with the device. At last the testing result and the diagram of the rectifying device are given.
