【摘要】 为了减小基于布里渊散射效应的扫描式频率测量系统的扫描次数,提出了基于游标效应的改进方案。分析了扫描式测频系统以及改进后系统的工作原理,通过引入具有不同自由光谱范围的复色泵浦光形成了周期性的增益谱。对基于游标效应的改进方案进行了仿真模拟,结果表明游标效应的引入大幅提升了系统的性能,降低了系统的扫描次数。更多还原

【Abstract】 To reduce the scanning number of frequency measurement system based on the effect of stimulated Brillouinscattering, an improved scheme by vernier effect was studied. The principles of both the original and improved system were studied, periodic gain spectrums were obtained by introducing multicolor pumps with different free spectral ranges. A simulation was carried out for the improved scheme, it shows that the introduceof vernier effect improves the performance of the system and reduces the scanning number.更多还原
