Speculations on televising many points simultaneously as elements of a line spectrum

A single ultrasonic cell carrying acoustic oscillations of many frequencies can deflect parallel light simultaneously in the many directions corresponding to these frequencies. When focused, the light beams form a line of spots corresponding to the acoustic spectrum. This correspondence proposes that the line of spots could usefully correspond to a line of television information, since each spot can be independently modulated in intensity. Frame scanning such a modulating line produces a complete picture. The system´s Fourier transform properties will cause noise interference and multipath propagation effects to be displayed in forms differing from those found in conventional serial transmission. A real image is available for video recording on film.
