摘要
In the novel method, the widths of the parallel luminescent stripes of a luminescent viewing screen are scanned by a beam of ultraviolet light whereby the stripes are excited to emit light along the path of scan. The emissions of the light in an identifying spectral band are sensed with respect to the position of the light beam on the screen and converted to a train of electrical signals. Then, the average width of the stripes identified by the spectral band is calculated from the distance over which the intensities of the signals are continuously above an assigned value.
