vibration detector

An explosion vibration parameter meter-model 702 detector and the proper measuring method are described in this paper.

本文主要介绍了一种爆炸振动测量仪&702型拾振器及其测试方法。

A direct mathematical expression for the relationship between the transmitter optics aperture and the satellite vibration amplitude has been derived. The assumption in the derived model is that the satellite communication system adapts on-off keying ( OOK) modulation and an APD as the detector.

从接收机的比特误码率与发射机的振动关系出发，采用OOK调制方式，以APD为光电探测器，推导得到了描述发射机天线口径与发射机振动关系的数学模型。

When the detector has a higher signal-to-noise ratio, we can decrease the local power of device to weak the external disturbance factors such as temperature, vibration.

经分析具有较高信噪比的探测装置可使用较低功率的本地光，从而减弱温度，振动等外界因素的干扰。
