چکیده

کاربردهای بسیار زیاد حسگرهای توزیعی فیبر نوری در صنایع مختلف منجر شده تا تلاش‌های زیادی برای بهبود خواص این حسگرها توسط محققان انجام شود. دقت تفکیک فضایی و طول سنجش ازجمله مهم‌ترین پارامترهای موجود در حسگرهای توزیعی فیبر نوری هستند که همواره مورد توجه مهندسان و کاربران این حسگرها بوده است. در بین این حسگرهای فیبری، حسگرهای بر مبنای پراکندگی رایلی به‌دلیل طول سنجش بسیار زیاد و حسگرهای بر مبنای پراکندگی بریلوئن به‌دلیل دقت فضایی بالا، هر یک طیف خاصی از کاربردها را پوشش می‌دهند. در میان حسگرهای بریلوئن، حسگر توری دینامیکی بریلوئن  (BDG) دارای بیشترین توان تفکیک فضایی است ولی کم بودن طول سنجش در این حسگر ازجمله معایب آن به حساب می‌آید. به همین دلیل تلاش برای افزایش طول سنجش در این حسگر یکی از اولویت‌ها برای محققانی است که در این زمینه مشغول مطالعه هستند. در این مقاله به کمک روشی جدید به نام ترکیب همبستگی فازی و فرکانسی، بیشترین طول سنجش در حسگر BDG برای دقت تفکیک فضایی در محدوده میلی‌متر شبیه‌سازی شده است. نتایج شبیه‌سازی نشان می‌دهد که می‌توان به کمک این حسگر به دقت تفکیک فضایی 9 میلی‌متر د در 7/17 کیلومتر از فیبر سنجش دست پیدا کرد.

چکیده [English]

Extensive applications of distribution fiber sensors in various industries have led researchers to make great efforts to improve the properties of these sensors. Spatial resolution and sensing length are considered among the most important parameters in fiber optic distribution sensor by engineers and users of these sensors. Among these fiber sensors, Rayleigh scattering-based sensors due to their very long sensing length and Brillouin scattering sensors due to their high spatial resolution, each cover a specific range of applications. Among Brillouin sensors, Brillouin dynamic grating (BDG) sensor has the highest spatial resolution, but the short sensing length of this sensor is one of its major disadvantages. For this reason, trying to increase the sensing length in this sensor is one of the priorities for researchers in this field. In this paper, using a new method called the combination of phase and frequency correlation, the maximum sensing length in the BDG sensor is simulated for spatial resolution in the range of millimeters. The simulation results show that with the help of this sensor, a spatial resolution of 9 mm over 17.7 km of the measurement fiber can be achieved.
