Abstract
A shock wave detection system includes an optical sensor configured to generate a sensor signal based on the received laser light, a processor, and a memory. The memory includes instructions stored thereon, which when executed by the processor cause the system to: generate a sensor signal based on the laser light; perform a digital fast Fourier transform on the sensor signal; determine a power spectral density of the sensor signal based on the digital fast Fourier transform; determine a difference in a frequency content before, during, and after a shock wave transition event based on the power spectral density; and determine a passing of the shock wave based on the difference in the frequency content.
