...mirrors are arranged so that red light from the red tube is reflected to the eye of the viewer from the red-reflecting mirror (see diagram). Blue light from the blue tube is reflected by the blue-reflecting mirror, but passes through the red-reflecting mirror to the eye. Green light from the green tube is not reflected at all. It reaches the eye direct. The viewer sees the three pictures superimposed so that they blend to form a full-color picture...
...substance) on the tube's face glows only in white light. But in front of the receiving set's picture tube is a second spinning "color disc" (see diagram). This disc is synchronized so that a blue segment is between the tube and the eye of the viewer whenever a "blue" field is flashing on the tube. So the eye sees the field in blue. When a "red" field is on the tube, a red segment of the disc makes that frame look red. In the same way, "green" fields are made to look-green. The three...
Next step is to combine the three colored images in the eye of the viewer. The combining is done with two "dichroic mirrors": plates of glass with one surface covered with a thin layer of a colorless, transparent substance. Because of the special way in which this combination affects light of different wave lengths, each mirror reflects only one color. The other two colors pass right through...
...retorts that definition isn't everything. More important, it claims, is the amount of "information" the picture conveys to the eye. The faithful colors in its system, CBS insists, give so much extra information that the viewer is glad to sacrifice a little definition...
...their comparative virtues. The solidest single fact is that the CBS system, developed to high perfection by Dr. Peter C. Goldmark, turns out pictures which are bright, crisp, and at least as faithful as most colored movies. Their own special ill is a so-called "color flash." If the viewer looks away suddenly, he sees the picture momentarily in a single color, because of the persistence in the eye of the last one-color picture seen. A color flash is seldom noticed unless it is looked...
