摘要： By using a sheet beam (26) and a charge-storing target (36) measuring differential of the deposited charge, one can greatly improve the performance of a scan converter (10). A segmented target (190) provides instantaneous analog output.

摘要： A cathode ray tube comprises a series of quadrupolar lenses for focusing a beam of electrons, emitted from a cathode at one end of an evacuated envelope under the control of a control electrode, at a target screen at the other end of the envelope. After having been focused at the target by adjustment of electric potentials on the quadrupolar lenses, the electron beam will defocus upon change in a potential on the control electrode because then the crossover or initial focusing point of the electron beam will be displaced along the central axis of the envelope. With a view to ready refocusing of the beam at the target, a refocusing lens is provided between the crossover point and the quadrupolar lenses for providing a convering lens action of radial symmetry about the envelope axis. The beam can be refocused through adjustment of a single potential on the refocusing lens rather than through adjustment of several different potentials on the quadrupolar lenses.

摘要翻译： 阴极射线管包括一系列四极透镜，用于在外壳的另一端处的目标屏幕处将来自阴极的阴极射出的电子束在控制电极的控制下聚焦在真空外壳的一端。 在通过调节四极透镜上的电位来聚焦在目标上之后，电子束将在控制电极上的电位变化时散焦，因为电子束的交叉或初始聚焦点将沿着中心轴 的信封。 为了使目标处的光束准备好再聚焦，在交叉点和四极透镜之间提供重聚焦透镜，以提供围绕包络轴的径向对称的会聚透镜作用。 可以通过调整重聚焦透镜上的单个电位来重新聚焦光束，而不是通过调整四极透镜上的几个不同的电位。
