改进的高灵敏度光声室频率特性的研究
Investigation of frequency property of improved high senstivity photoacoustic cell
摘要
采用被测样品本身做光声室窗,并采用反射镜将透射光反射回样品,使光声信号提高了1.5倍,用此光声室对单晶硅的频率特性进行了研究,其理论计算和实验结果符合得较好。
Abstract
We put a sample on the top of photoacoustic cell as a window of it and used a goldcoating high reflectianee mirror by which light beam was reflected back to the sample, the photoacoustic signal is enhanced as much as 1.5 times. By the above photoacoustic cell, we investigated the frequency property of the crystal Si and the experimental results are in good agreement with the theoretical calculation.
