Utilizing Optic Fiber Interferometry in Forced Vibration Experimentation for Educational Purposes
Year: 2025
Type: preprint
Abstract: This study introduces an experimental teaching method that employs optic fiber interferometry (OFI) to investigate forced vibration phenomena. It is designed for undergraduate physics majors with foundational mechanics and optics training and optics-focused graduate students. This approach aims to deepen students' understanding of forced vibration theory and interferometric measurement principles while fostering skills in experimental design, data analysis, and problem solving. Leveraging OFI's high-precision displacement measurement capabilities, the experiment enabled accurate tracking of frequency and displacement variations. By scanning the driving force frequency, students obtained amplitude frequency curves to determine the system's natural frequency, which closely aligned with theoretical predictions. This method may bridge theoretical concepts and practical applications, offering insights into teaching vibration theory and precision measurement techniques and equipping students with integrated knowledge for real-world challenges.
