Thanks to God and His grace, two scientific papers were published in the first quarter (Q1) of the WoS database in the field of sensing and early warning technologies using optical fibers. This was done with the participation of Libyan researchers from the College of Electrical and Electronic Technology in Benghazi and the College of Engineering at Gharyan University, within the Photonics and Optical Fiber Technologies team at the National University of Malaysia (Universiti Kebangsaan Malaysia, UKM). The first paper was published in the journal Sensors, part of the MDPI group, led by Dr. Mohamed Al-Qaoud, a faculty member at our college, as the main researcher and author. In this paper, the team employed multiple versions of digital filters to reduce noise and signal distortion resulting from the use of complementary pairs in quasi-distributed optical fiber sensors. The second paper was published in the IEEE Access journal and was led by Dr. Abdelfattah Abu Shaqour from the College of Engineering at Gharyan University as the principal author and originator of the idea. In this study, the team demonstrated the feasibility of a new method proposed by Dr. Abdelfattah in his previous work, which involves modifying the cutoff frequency of the FBG filter to measure two physical quantities with a single sensor. The study will open the possibility of measuring three physical quantities with one sensor.
