Abstract

Aiming at the feasibility of the ultrasonic sensing technology applied in the mars environment, a measurement method of ultrasonic velocity in the low pressure of CO₂ environment based on the optical fiber Fabry-Perot vibration sensor was proposed. An ultrasonic velocity test system has been designed and implemented. The pressure in the chamber was adjusted from 600 Pa to 1 MPa with different intervals, using four pairs of piezoelectric actuators and sensors, with central frequencies being 21, 25, 34, and 40 kHz respectively, and was applied to generate ultrasonic signals. The experimental results show that, the optical fiber Fabry-Perot (F-P) pressure sensor can adapt to the low pressure environment and can still receive the ultrasonic signals in 600 Pa CO₂ environment. The ultrasonic velocity rarely varies with the pressure in the range from 600 Pa to 1 MPa, while it depends on the composition of the gas and the temperature. The ultrasonic velocity in atmosphere is 336.18 m/s, which is travel faster than in CO₂ environment 268.79 m/s, and the ultrasonic velocity in 15 ℃, 600 Pa CO₂ environment is 271.51 m/s.
