【Abstract】 A method for real-time reconstruction of the beam spot profiles in the shadow mask CRT is proud in this paper. The deflection system that provides the micro tranSlation for the spot reconstruction is described in detail. The method for calibrating the deflection sensitivity is the provided. The original beam spot profile that is separated by the shadoW mask is obtained from the masked beam spot on the screen.更多还原
