微型光波导陀螺中光源线宽影响系统的分辨率和灵敏度 ,通过理论分析和实验 ,把光栅周期变化 量子阱 分布反馈 (CPM MQW DFB)激光器作为光源来压窄线宽是比较理想的
The linewidth of light source in micro-optic waveguide gyro affects the resolution and sensitivity of the system. It is ideal to narrow the linewidth by using grating periodic-change quantum well distributed feedback (CPM MQW DFB) laser as light source through theoretical analysis and experiment
