摘要
设计了一套可以用来测量弱脉冲光时域噪声信息的平衡零拍探测系统,通过对本底光散粒噪声基准的测量分析了该系统的各项性能指标,并且对弱相干光脉冲进行了正交位相振幅分量的噪声测量。
A time-domain balanced homodyne detection system for weak pulse is designed. The performance is analyzed through the measurement of shot noise limit to local oscillation. Finally, a we.ak coherent light is measured and the quadrature component is obtained.
