Real-Time Location of Impact on a Planar Surface
Abstract
A proof-of-principle integrated hardware-software system has been developed which rapidly measures impact locations on a planar surface. This device operates by measuring the rate of charge transfer along an electrically resistive sheet from the point of impact to a series of charge collection tabs. Both one-dimensional and two-dimensional transducer geometries have been investigated. A collection of calibration and correction software routines has been developed to increase impact location accuracy. The performance of this system has been evaluated for both laboratory and simulated field conditions. Multihit capability has been investigated by evaluating system performance with damaged transducer surfaces. Schematic diagrams are included of all electronic circuitry as well as listings of all software routines.
