Abstract
A light pen is provided with an elongated or spatula-shaped light receiving end which houses a plurality of optical fiber tubes in either a linear or two-dimensional array. The device is useful for simultaneously reading the coordinates of a plurality of points within a single scan period of a CRT image produced using the NTSC system. A slideable light interceptor may be provided in the operator of the light pen so as to limit the size or the proportion of the array receiving incident light.
