Abstract

To obtain high quality optoelectronic image devices, the phosphor screens should be evaluated before assembled in the devices. The principle and method of measurement are expounded. A measurement system is developed, which can measure luminous efficiency, luminance, non-uniformity of luminance and persistence of phosphor screen. It can also detect the flaws of screen. The system consists of vacuum chamber, electron gun, electrostatic lens system, high voltage supply, imaging luminance meter, luminous flux tester, control units, signal processing circuit, A/D converter, D/A converter, communication unit, industrial computer and measurement software.
