Abstract : The newest problem in television for space is the development of a single system which will incorporate the best features of the presently implied three distinct systems for conveying the images of 'cosmic bodies' over great distances. The 'single-element' system collects the light flux from an 'elementary' area of the observed surface through mechanical scanning and converts it into current by means of a photomultiplier tube, after which it is handled as a video signal; the 'phototelevision system,' implies a photographic method with camera, film, developer, plus film reader; the 'small frame system,' employs frequency-band compression based on the elimination of the subjective redundancies of photographed images by means of a camera shutter; these have different advantages and disadvantages and are used for different desired results. Combining them into a single system for all TV transmission from space seems out of the question at the present time. The article gives the fundamentals of the three types of operation, block diagrams and a photograph of a phototelevision system. (Author)
