In-Situ Explosion Shockwave Sensor


An impact sensor device and method to measure multiple explosion reaction zone data points in real-time during live explosive testing experiments.

Measuring how explosion shockwaves behave in different materials is key to studying their potential impact on surrounding areas. Traditional methods utilize flash x-rays, embedded pressure gauges, or timing pins. These methods become cost-prohibitive or technically inadequate in large-scale explosion experiments that exceed 100 pounds of explosive material.

The Fiber Light Relay System (FLRS) is an explosion impact sensor and software system that provides a simple, cost-effective method to collect and analyze shock measurements. When the explosive detonates, the fiber optic cable relays the shock output to a camera where the data is collected to calculate shock velocity and shock wave shape. This system can record data from hundreds of points with one or two cameras while the python software provides an accurate picture of the shock wave shape and travel behavior.
