Ultra-high velocity projectile impact sensor

Abstract

An apparatus for detecting the impact of an ultra-high velocity projectile includes: a projectile; at least one optical fiber attached to at least a first area of the projectile; a light source coupled to the optical fiber supplying light into the optical fiber; and a monitor coupled to optical fiber configured to monitor the light in one optical fiber and positioned in a second area of the projectile. A method for operating a circuit in response to a shockwave of ultra-high velocity, includes the steps of deploying at least one optical fiber in a first area in the path of an ultra-high velocity shockwave; coupling a light source to the optical fiber, the light source supplying a light into the optical fiber; and deploying a monitor coupled to the optical fiber to: monitor the light in the optical fiber to detect a change in the light; and positioned in a second area further along the path of the shockwave.
