Evaluation of Cathode-Ray Tube Protection and Antireflective Surfaces for the Plan View Display.

Abstract

The purpose of this report is to describe the evaluation of implosion protection systems and antireflective surfaces for cathode-ray tube (CRT) used in plan view displays (PVD's) for air traffic control (ATC). An implosion forcing device was fabricated utilizing coolant spray and a carbide-tipped punch to impact the critical CRT shoulder area to induce implosions. Results showed that none of the six CRT's tested utilizing the Kimcode -type implosion system could be imploded violently. Ten other CRT's were evaluated for antireflectivity and optimum resolution. Various antireflective surfaces were tried. Subjective analysis indicated that an etched surface was sufficient to reduce reflections for ATC use. The combination of etch and High Efficiency Antireflective (HEA) coating was judged most antireflective, but fingerprints on the HEA-coated surface could be seen. (Author)
