摘要
简要介绍了激光陀螺闭锁阈值的产生及测试原理,通过对传统激光陀螺闭锁阈值测试系统的分析,给出了基于虚拟仪器的闭锁阈值测试方案。经过实际测试,新的闭锁阈值测试系统可实现自动化测试,测试时间由原来的十几分钟缩短为20 s,测试误差小于10 Hz。
The principles of the producing and testing of the ring laser gyroscope are presented briefly in this paper. Through analyzing the test system of the dead zone, the dead zone test plan based on the virtual instrument technology is given. Going through the practical test, the new dead zone system can realize the autotest. The test time can be shortened from over 10 minutes to only 20 seconds. The uncertainty of the test result is less than 10 Hz.
