Abstract:The vibration sensors with high sensitivity and wide frequency range have a large application demand for in the engineering project. Combining with the advantages of optical fiber sensor monitoring technique, in the paper, a kind of optical fiber Fabry-Perot (F-P) vibration sensor has been designed based on the differential-type structure of the double V-shaped cantilever a optical fiber F-P cavity. Through two different differential vibration of the cantilever beam, change the F-P cavity length, the realizati… Show more
“…This also provides a basis for developing ultrasonic anemometers, exploring applications of ultrasonic sensing technology in detection and early warning systems for vehicles on Mars, and answering key questions such as whether sounds can be transmitted in the atmosphere of Mars [13]. The optical fiber Fabry-Perot (F-P) sensor has high sensitivity and can avoid the effect of electromagnetic interference and low-pressure discharge [14][15][16], which makes it an accurate and effective acoustic vibration monitoring sensor [17][18][19][20]. In this study, we set up a test system for measuring ultrasonic in a lowpressure gas.…”
