resulting from scanning during a black picture (zero amplitude of the 50 megacycle sine wave) signal produce grooves in the oil which cause deflection of the light beam along the Schlieren strips so that still no light passes through to the projection lens. Finally, in an area where the 50 megacycle sine wave is present, causing dimpling along the scanning line, light is deflected at right angles to the Schlieren strips, thus permitting the particular bundle of light to pass through the projection lens which images it on the screen. The amount of this light is proportional to the amplitude of the 50 megacycle sine wave.

In essence, then, the Schlieren strips act as a variable iris whose opening is different for each elemental area of the raster and depends on the surface conditions thereon. As in most irises, the location of those strips is as close to the center of the projection lens as is possible.


All those who saw the demonstrations of Eidophor held in New York, were firmly convinced that from the technical and mechanical point of view this new color TV system had just about arrived. However, this brings up a very important question: Just what will Eidophor mean to the industry?

A few voices were raised doubting just how much of an impact Eidophor will

have in the long run. One of these was Bosley Crowther, motion picture critic for the New York Times. After attending a session of Eidophor, Crowther admitted that "the system looks surprisingly good}' However, he questioned what advantage large-screen color television had over a Technicolor film, other than transporting an image more quickly from its source.

Crowther agreed that the drawing power of special programs, such as top sporting events, has proven to be a profitable enterprise as far as large screen theatre television is concerned. However, he doubted if the public would go for a steady diet of Eidophor shows on a regular basis, even if they were of top notch caliber, once the initial novelty wore off.

The Bright Side

Despite the protests of a few, most of those who have seen Eidophor seem to be of the opinion that it has a tremendv ous potential. From the standpoint of theatre audiences, Eidophor offers two important aspects. First, the entertaine ment it will provide will be enhanced in its appeal to patrons because live shows

and events, plus motion pictures, will be instantaneously transmitted from a central point of origin to hundreds, and even thousands of theatres, simultaneously. Therefore, the element of immediacy is added to that of unlimited range in the type of entertainment made possible.

The second point is that Eidophor is said to project moving images with a perfection equal to, if not superior to, the present film motion picture projection, and transmits color with startling fidelity to the natural tints of flesh, costumes and nature, no matter how rapid the action be.

Every patron, no matter where his theatre is located, will have the equivalent of a front row seat for all the latest and finest entertainment, ranging from top motion pictures to new Broadway shows, top popular singers, opera, etc.

The Exhibitor

From the standpoint of the theatre exhibitor, Eidophor can be of uppermost importance because it will put at his disposal attractions heretofore beyond the reach of theatres located outside of the largest cities. All that is new and up-to THEATRE CATALOG 1953-54
