AI Article Synopsis

  • The paper presents a compact and cost-effective interferometric sensor that utilizes the self-mixing effect in laser cavities to characterize shock waves.
  • The sensor measures changes in refractive index caused by shock waves and operates using a self-mixing interferometry scheme.
  • The authors detail the sensor's design, the experimental setup involving a shock tube, and present measurements of shock wave pressure amplitude at 5 bar, interpreting the results in relation to existing acousto-optics models.

Article Abstract

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 induced by the shock wave. It is based on the self-mixing interferometry scheme. We describe the architecture of the dynamic sensor and the design of the experimental setup used for the characterization that involves a shock tube. Thus, we detail the experimental measurements for shock wave pressure amplitude of 5 bar and address their interpretation with regard to the most admitted models for acousto-optics.
