目的：研究激光功率计在进行电磁兼容抗扰度测试中的抗扰情况，以提高测试准确性。方法分别对氦氖激光器和光学纤维喉镜两种医用电气设备进行电磁兼容辐射抗扰度测试，使用两种常用激光功率计进行输出光测量，观察不同激光功率计在不同输出条件下的功率检测情况。结果在相同环境条件下，不同激光功率计的辐射抗扰度差别较大。结论在进行电磁兼容抗扰度测试前，应对激光功率计进行辐射抗扰度测试，以避免检测时因检测设备本身受到电磁场的影响而引发的对实验结果的误判。

Objective To make a research on the anti-interference situation of laser power meter during EMC anti-interference test so as to improve the testing accuracy. Methods Two kinds of commonly-used laser power meters were used to measure the output light in the EMC anti-interference test respectively for He-Ne laser and optical ifber laryngoscope. The power inspection situation of different laser power meter was observed in variant output conditions. Results Radiated anti-interference of different laser power meter differed quite a lot under the same environmental conditions. Conclusion The radiated anti-interference test on laser power meter should be made before the entire test in order to reduce misjudgment of experiment result caused by the effect of electromagnetic ifeld on the test equipment.
