چکیده .

در سالهای اخیر، روشهای مبتنی بر حسگر فیبر نوری توزیع‌شده (DFOS) با توجه به مزایایی همچون ایمنی در برابر تداخل امواج الکترومغناطیسی و ایجاد امکان سنجش توزیعی، مورد توجه قرار گرفتهاند. از جمله این روشها میتوان به حسگرهای مبتنی بر اثر پراکندگی رایلی اشاره کرد. از DFOS مبتنی بر اثر پسپراکندگی رایلی میتوان برای حسگری لرزش که روشی امیدوارکننده برای کاربردهای مختلف، از جمله حفاظت پیرامونی و نظارت بر خطوط لوله است؛ استفاده کرد. حسگر مبتنی بر اثر پسپراکندگی رایلی در دو دسته بازتابسنجی نوری حوزه زمان (OTDR) و بازتابسنجی نوری حوزه فرکانس (OFDR) طبقهبندی میشود. روش OFDR، علیرغم پیچیدگی بالاتر، با توجه به مزایایی که در بهبود وضوح مکانی در کنار SNR مناسب دارد، به عنوان یک جایگزین برای OTDR معمولی مطرح است. در این مقاله، یک روش حسگری لرزش مبتنی بر OFDR یعنی روش میانگین قدرمطلق تفاضل دو سیگنال به روش بازتابسنجی حوزه فرکانس با محدوده وضوح 2/1 متری معرفی و ارزیابی شده و با استفاده از نرمافزار MATLAB شبیهسازی و بررسی میشود. با توجه به نتایج حاصل از بررسی، روش ارائه‌شده به‌عنوان روشی مبتنی بر OFDR برای آشکارسازی رویداد لرزشی مناسب ارزیابی‌شده است.

چکیده . [English]

In recent years, Distributed Fiber Optic Sensors (DFOS) have received attention due to advantages such as immunity to electromagnetic interference and distributed sensing capability. Among these methods, we can mention the sensors based on the Rayleigh scattering effect. DFOS based on the Rayleigh backscattering effect can be used for vibration sensing, which is a promising method for various applications such as perimeter security and monitoring of pipelines. The sensors based on the Rayleigh backscattering effect is classified into two categories: Optical Time Domain Reflectometry (OTDR) and Optical Frequency Domain Reflectometry (OFDR). The OFDR method, despite its higher complexity, is proposed as an alternative technique to the conventional OTDR in order to improve the spatial resolution without sacrificing the SNR. In this article, a vibration sensing method based on OFDR, i.e., the average of the absolute magnitude of the difference between two signals obtained through optical frequency domain reflectometry with a resolution of 1.2 meters is investigated and evaluated. This method is investigated, evaluated and simulated using MATLAB software tool. According to the results, the proposed OFDR-based method, has been evaluated as a suitable method for detecting vibration events.
