Abstract

This study introduces a high-resolution optical fiber underwater acoustic sensor utilizing a Fabry-Perot (FP) interferometer design. The sensor consists of a single-mode fiber (SMF) integrated with polydimethylsiloxane (PDMS), forming an FP cavity at the coated SMF terminus. The exceptional elasticity of PDMS amplifies vibrations from acoustic stimuli, modulating the FP cavity for effective acoustic wave detection. This integration of the probe within a single fiber, along with the PDMS coating technique, enhances the sensor’s SNR, resolution, and frequency response. The sensor’s simplicity, cost-effectiveness, superior signal-to-noise ratio, and low power consumption make it a promising tool for underwater acoustic applications.

通过 PDMS 涂层增强高分辨率光纤水下声学传感器

本研究介绍了一种利用法布里-珀罗（FP）干涉仪设计的高分辨率光纤水下声学传感器。该传感器由一根集成了聚二甲基硅氧烷（PDMS）的单模光纤（SMF）组成，在涂有聚二甲基硅氧烷的单模光纤末端形成一个 FP 腔。PDMS 的超强弹性可放大声刺激产生的振动，从而调节 FP 腔，实现有效的声波探测。探头与 PDMS 涂层技术集成在一根光纤中，提高了传感器的信噪比、分辨率和频率响应。该传感器操作简单、成本效益高、信噪比优越且功耗低，是水下声学应用的理想工具。

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
