In this paper, a neural network approach is applied for solving an electromagnetic inverse problem involving solid dielectric materials subjected to shock impacts and interrogated by a millimeter-wave interferometer. Under mechanical impact, a shock

In this paper, we demonstrate that a compact and inexpensive interferometric sensor based on the self-mixing effect in the laser cavity can be used for the characterization of shock waves. The sensor measures the changes in the refractive index induc

Shock and detonation velocities are today measured continuously using long silica chirped fiber Bragg gratings (CFBGs). These thin probes can be directly inserted into high-explosive samples. The use of a polymer fiber increases the sensitivity at lo

Dynamic measurements of shock and detonation velocities are performed using long chirped fiber Bragg gratings (CFBGs). Such thin probes, with a diameter of typically 125 µm or even 80 µm can be directly inserted into high-explosive (HE) samples or

Multiplexed photonic Doppler velocimetry is required to measure 2D surface velocities of novel materials in shock physics experiments. Very close measurements lead to crosstalk issues, which can be fixed by wavelength multiplexing. The benefits of ou
