Laser-induced shock wave two-dimensional extraction technology based on a beam deflection method.

This paper introduces a method for analyzing the spatiotemporal progression of laser-induced shock waves using the beam deflection technique. This method allows for the accurate measurement of the shock wave evolution and can replace high-speed cameras. The results demonstrate the detection signals at various distances and energies, as well as the extraction and reconstruction of the shock wave velocities and propagation trajectories. The characteristic velocities of the shock waves propagating in air from various metals and energetic materials were measured and compared with the results obtained from high-speed cameras. The study also predicts the macroscopic detonation velocity of energetic materials based on the characteristic velocity. Overall, this approach offers a reliable and cost-effective method for studying the shock waves and has potential applications in various fields.
