摘要：

A novel fiber optic pressure sensing technology is presented to obtain the peak reflected pressure of shock waves. This technology is based on the Newton's second law and the pressure relates directly to the acceleration of a thin diaphragm. The acceleration is detected by an interferometric measurement of the displacement using a Fabry-Perot cavity technology. Both numerical simulation and shock tube experiments prove that the pressure sensing technology is feasible. And this technology has several advantages including no calibration required, ease of manufacture, low cost, high precision and fast response times. © 2019, Editorial Staff of EXPLOSION AND SHOCK WAVES.
