摘　　要：与拉曼光谱等光谱测试分析方法相比,布里渊光谱可反映测试样品弹性系数等力学性能。采用中心波长为532nm的单纵模激光器作为激发源,使用扫描型多通道双串联式法布里-珀罗干涉仪对产生的布里渊光进行探测,成功搭建了一套共焦布里渊光谱测试装置。系统利用具有远程通信功能的套接字端口方式获取光子数,进行光谱采集和显示。该方法可进一步应用于与共焦布里渊显微成像相关的大型系统远程联动装置,在仪器设计方面具有广阔的应用前景。利用该套基于套接字编程的共焦布里渊光谱测试装置,测得树脂玻璃、硅胶和二氧化硅玻璃的布里渊光谱,并计算得到相应的纵向弹性系数。Compared with the spectrum test methods, such as the Raman spectroscopy, the Brillouin spectroscopy can reflect the mechanical properties including elasticity coefficient. By using a single-mode 532 nm laser as the excitation source, and a scanning multi-channel tandem Fabry-Perot interferometer to detect the Brillouin light, a confocal Brillouin spectrum test system has been successfully built. This system uses the socket port means with telecommunication function to acquire the photon counts and realize spectrum acquisition and display. This means is expected to be further applied to large-scale remote linkage setup related to confoeal Brillouin imaging, and is a prosperous instrument design direction. Based on this confocal Brillouin spectrum test setup with socket programming, the BriUouin light of resin glass, silicon rubber and glass are obtained, and the corresponding longitudinal elasticity coefficients are calculated.
