基于虚拟仪器技术的布里渊自动探测系统设计

摘要

Using the theory of stimulated brillouin scattering and virtual instruments technology a new automatic-detection system of stimulated brillouin scattering is designed. LabVIEW is utilized to control instruments of experiment, LabVIEW programme and partial hardware circuit are designed, the change of stimulated brillouin scattering signal is analyzed in different depth by ICCD. Not only pro-posed one kind ofnew detection system, moreover has given the detailed theoretical foundation to the system. This new detection system effectively solved the error that because of the human factor, and the detcction depth and precision can be enhanced distinctly.%将虚拟仪器技术与受激布里渊散射理论相结合,提出一种新型的布里渊散射自动探测系统.利用功能强大的Lab-VIEW作为软件设计平台,对各种仪器进行实时精确的控制.设计了各个系统单元的LabVIEW控制程序以及部分硬件电路,测量并分析在不同深度下,ICCD接受到的受激布里渊散射回波信号的变化情况,提出了一种新型的探测系统,并对探测系统给出了详细的理论分析.新型的受激布里渊探测系统能有效地解决实验中人为因素造成的误差,提高了探测的深度和探测精度.
