【摘要】 位置敏感探测器(Position Sensitive Detector,简称PSD)作为振动检测器件应用于三维主动振动控制系统中,建立了系统的数学模型。对检测过程中遇到的具体问题(如光源的选择、背景光的影响、装置转动的影响等)进行了分析,并给出了相应的解决措施。对PSD信号处理电路做了简单介绍。更多还原

【Abstract】 Position sensitive detectors are used in a three dimensional active vibration control system as vibration detective components. The system mathematical model is established. Some material problems are analyzed, such as the selection of LED, the effect of background light and equipment turning. The solution measures are presented accordingly. The signal processing circuit of PSD is introduced.更多还原
