Paper Abstract

Based on modulation transfer function (MTF), a CRT projection tube resolution measurement system has been developed. This system features auto optical focusing and voltage focusing. It has high resolution, fast measuring speed and friendly operation interface. The results indicate that the error of the system is within ±4% by measuring the standard optical slit ranging 30μm to 500μm, while repeatability is better than 95%. Moreover, the measured data demonstrate that the resolution of YAG projection tube can meet the demands of HDTV.
