Abstract: A high energy laser target board substrate system having a substrate substantially transparent to one or more forms or radiation, includes a diffused first surface and a reflective layer with a transmissivity at a zero-degree angle of incidence greater than 0.0% with transmissivity decreasing thereafter as angle of incidence increases.

Abstract: An impact detection system according to the present invention includes an impact sensor, damage sensors and an electronics package. The impact sensor includes a fiber optic grid preferably attached to a target object to detect impact locations on the target. The damage sensors measure damage sustained by the object, while the electronics package monitors the fiber optic grid, records the impact location and sends information pertaining to the impact location and target damage through a telemetry link with limited bandwidth to a receiving station. In order to ensure transmission of desired information, the electronics package allocates telemetry bandwidth to sensor information most relevant to impact location and target damage to enable transmission in the limited time interval available prior to target destruction or impact detection system disablement. This is accomplished by dynamically allocating reporting priority to different sensors during an impact.
