虚拟仪器实现自扫描光电二极管列阵信号峰值的采集

Signal Peak Acquisition of Self scanning Photodiode Array Based on Virtual Instruments

采用虚拟仪器的方式，在速度较低的采集卡上快速、简便而准确地实现了自扫描光电二极管信号峰值的采集，提出了两种实现方法。并通过实验证实了其中用ＳＳＰＤ延时后的φ时钟代替数据采集卡内部时钟，完成ＳＳＰＤ信号峰值采集的方法是可行的。

The signal peak acquisiton of self scanning photodiode array based on virtual instruments is realized and two methods are presented.It is proved feasible to replace the internal clock of data acquisition board with delayed φ clock of SSPD to realize the signal peak acquisition.
