Wireless Transmission of Friedlander-Type Signals for the Dynamic Measurement of Blast Pressure

Mathieu Chalnot et al.

Summary: This paper discusses the limitations of wired transmission of blast pressure signals delivered by sensors and proposes a new wireless solution for dynamic measurement. Experimental results confirm that the measurement bandwidth of the wireless setup is not limited by distance, paving the way for dynamic measurement of blast pressure variations during explosions.

Miniature High-Frequency Response, High- Pressure -Range Dynamic Pressure Sensor Based on All-Silica Optical Fiber Fabry-Perot Cavity

Chenglei Chu et al.

Summary: A miniature shock-wave pressure sensor based on an optical-fiber tip F-P cavity is described in this paper, and its transient interferometric phase is demodulated using passive homodyne demodulation technique. The static and dynamic calibration tests show that the sensor has good linearity, repeatability, and hysteresis within the 1 MPa pressure range.
