摘要

介绍了一种用于测量不同振动频率和驱动电压的环形激光传感器的理论和实验演示。在环形激光的光路中，基于EYDF的传感单元既是传感器又是滤光器。在0 ~ 1 MHz的振动频率上进行了实验，结果表明在1 ~ 48 kHz范围内可以实现振动传感。不同振动频率的方波信号和正弦波信号分别作用于传感器。在4 kHz、5 kHz、7 kHz、8 kHz和10 kHz的方波输出光信号以及4 kHz、7 kHz、8 kHz和33 kHz的正弦信号中观察到显著的光强变化和波长位移。传感器波形识别清晰，完成了实验系统的稳定性测试。所提出的振动传感器可用于交通运输工程、精密仪器检测等领域。

A ring cavity laser sensor for measuring different vibration frequencies and driving voltages

A theoretical and experimental demonstration of a ring laser sensor for measuring different vibration frequencies and driving voltages is presented. In the light path of the ring laser, the sensing unit based on EYDF serves as both a sensor and a filter. Experiments are conducted on 0 ∼ 1 MHz vibration frequency, and the results show that vibration sensing can be realized within 1 ∼ 48 kHz. Square wave signals and sine wave signals with different vibration frequencies are applied to the sensors. Significant light intensity variations and wavelength shift are observed in the output optical signals at 4 kHz, 5 kHz, 7 kHz, 8 kHz and 10 kHz for square waves and at 4 kHz, 7 kHz, 8 kHz and 33 kHz for sinusoidal signals. The sensor clearly exhibits waveform recognition and the stability test of the experimental system is completed. The proposed vibration sensors can be used in the fields of transportation engineering, precision instrument detection and so on.

期刊介绍： The Journal covers the entire field of infrared physics and technology: theory, experiment, application, devices and instrumentation. Infrared'' is defined as covering the near, mid and far infrared (terahertz) regions from 0.75um (750nm) to 1mm (300GHz.) Submissions in the 300GHz to 100GHz region may be accepted at the editors discretion if their content is relevant to shorter wavelengths. Submissions must be primarily concerned with and directly relevant to this spectral region. Its core topics can be summarized as the generation, propagation and detection, of infrared radiation; the associated optics, materials and devices; and its use in all fields of science, industry, engineering and medicine. Infrared techniques occur in many different fields, notably spectroscopy and interferometry; material characterization and processing; atmospheric physics, astronomy and space research. Scientific aspects include lasers, quantum optics, quantum electronics, image processing and semiconductor physics. Some important applications are medical diagnostics and treatment, industrial inspection and environmental monitoring.
