چکیده
سنسور پنجره براگ در فایبر نازک شده امروزه به دلایلی ازجمله حساسیت بالا، عدم تأثیرپذیری از ساحه های الکترومقناطیسی، خطی بودن و سّبک، کاربردهای زیادی در صنعت برای تشخیص سلامت ساختمانهای میخانیکی پیداکرده است. محدودیتی که در استفاده از وجود دارد این است که پاسخ سنسور به درجه حرارت و فشار بهصورت همزمان میتواند باعث ایجاد خطا در اندازهگیری فشار در ساختمانهای مختلف گردد. به این منظور باید بطریقه أی اثر درجه حرارت را از اثر فشار تفکیک کنیم. در این مقاله، با طراحی سنسوری ترکیبی فایبر نوری نازک شده و راهکاری برای حل این مشکل ارائه داده ایم. بررسیهای انجامشده روی سنسوری ترکیبی طراحیشده نشان میدهد تداخل حساسیت در سنسور مذکور ایجاد نخواهد شد. در سنسور ترکیبی مذکور، سنسور فایبر نوری نازک شده با حساسیت درجه حرارتی و سنسور با حساسیت درجه حرارتي و فشار به ترتیب و به كار گرفته شده اند.
