提出了一种在参量采样门中消除泵浦噪声传递的新技术。该方法依赖于在混合过程之后对泵和惰轮的同时检测。检测到的泵浦波动用于抑制在参量混频过程中传递的闲频变化。一个11分贝的改善，在空闲的电气信号噪声比的实验证明。
A new technique for pump-noise transfer cancellation in parametric sampling gates is presented. The method relies on simultaneous detections of the pump and the idler after the mixing process. The detected pump fluctuations are used to suppress the idler variations transferred during the parametric mixing process. An 11-dB improvement in idler electrical signal-to-noise ratio is demonstrated experimentally.
