摘要

根据光声信号激励基本原理与传输线理论

应用声电类比方法

提出了基于声学传播模型的一维纵向谐振腔传输线模型。根据实际设计需求

改进并提出一维纵向光声池整体模型。应用所建传输线模型对一维纵向光声池谐振频率、品质因数、池常数等指标与光声池结构参数关系进行模拟分析与讨论。结果表明

光声信号强度与一维谐振腔长度及光源调制频率具有相关性

且随谐振腔长度增加

光声池谐振频率具有减小的趋势;存在最优光声腔截面半径使与一定谐振腔长度对应的品质因数取得最大值。模拟结果对一维纵向光声池结构设计具有较高指导意义。

Abstract

According to the principle of photoacoustic（PA） gas detection and transmission line

this paper presented and improved model of one-dimension PA cell signal transmission line with analogy analysis. The model simulation presented the resonant frequency

quality factor and cell constant of PA cell. It also presented the relationship between these performance indexes of PA cell and its geometrical parameters. The model simulation results show that the correlation can be found between lengths of resonant cavity and resonant frequency

and the correlation between lengths and radius of resonant cavity also can be found. The model simulation has high theoretical instructive significance.
