1 There is an accelerating trend toward greater realism in media communications. This trend can be attributed to technological innovations.
2 Years ago the radio sounded brassy and full of static. Now, since the development of frequency modulation (FM), radio sound is of a much higher fidelity. Stereophonic sound (stereo), another technological innovation, was a further step toward an improvement in the method of retaining naturalness in sound.
3 Perhaps a greater advance in the trend toward realism in communications was the invention of television. Wall to Wall television with panels for a cinematic effect may indeed be what tomorrow holds in store for us. Only three-dimensional and true-size projection remains to be developed in the continuing search for realism in visual communications.
4 It was not until 1960 that the first major breakthrough in the capability for the production of a practical stereoscopic system took place. At the time, the invention of the laser ray, which incorporated the principles of light and radio radiation, was utilized by communications media technicians. With the laser ray, which created an energy form known as electromagnetic radiation, it became possible to record the actual distance from each object to the photographic plate. This finished plate, called a hologram (whole picture), permits three-dimensional viewing.
5 The only areas not yet near perfection in the technological communication search for realism are the sensations of touch, taste, and smell. Who knows what sensations of realism we may yet experience in the communications world of tomorrow?
What invention incorporated the principles of light and radio radiation?
