Disposed over the plate is a layer of elastoluminescent material composed of zinc sulfide and manganese embedded in an elastomeric composite. This luminescent material is designed to emit light or exhibit luminescence when elastically strained, for example when a projectile strikes the material. Optical photosensitive sensors are deployed at strategic locations to observe and record color images of the target before during and after impact by a projectile. These images capture the target luminescence and impact location of the projectile. The images are transmitted to a traditional image processing system that can isolate the impact location and correlate the light wave length with a known kinetic energy value that was obtained through initial calibration of the system.Other References
