Use of an Electrolytic Tank in Study of Surface Electric Field Distributions
Abstract
Previous two-dimensional electrical field experiments, involving glass disks covered on one side with a transparent conductive coating, disclosed that commercially available glass samples had a distinct nonuniform resistivity across the face of individual pieces. Using an electrolytic tank of analogous electrical characteristics with twenty-four peripheral electrodes connected to a suitable source, it was determined that probe voltage would, with negligible error, be proportional to probe coordinates within a working circle whose normalized diameter is 0.8. Either rectangular or polar coordinates can be used, but resistive glass coating must be sufficiently uniform for such an operation. An important application of the transparent , electrically conductive disk is the rapid, multiple designation of the coordinates of a target seen on a search-radar PPI indicator to a fire-control radar. Such a system is under development at this laboratory.
