Abstract

This article is devoted to the study of the influence of acoustic environmental impacts on the operation of fiber-optic interferometers and measuring systems that are based on them. A method for reducing this influence by using an acoustically conditioned sound-proofing case for operation in the presence of external impacts in a frequency range of 20 to 20 000 Hz is considered. A mathematical model and the results of its research are presented; the calculated dependence of the degree of reducing the acoustic sensitivity of a fiber-optic interferometer on the degree of acoustic sealing of its case is obtained. An experimental setup and a technique for experimental evaluation of the degree of acoustic sealing when studying the cases of devices were developed.

光纤干涉仪声调保护箱的声密封度对其特性的影响研究

摘要

本文致力于研究声学环境影响对光纤干涉仪和基于它们的测量系统的运行的影响。考虑了一种通过使用经过隔音处理的隔音箱来减少这种影响的方法，该隔音箱用于在20到20 000 Hz频率范围内存在外部撞击的情况下进行操作。给出了数学模型及其研究结果；得到减小的光纤干涉仪的声灵敏度的程度与其外壳的声密封程度的计算关系。在研究设备的情况时，开发了一种实验装置和一种用于评估声密封程度的技术。
