The author proposes to base the synthetic reproduction of the
television picture upon the optical and physiological actions of
the motion picture projector of Mechau. This idea rests up on the
high amount of correlation existing between the sequential images
and on the inert visual perception of man, i. e. two facts which
favour the introduction of an electrostatic memory device capable
of modulating on each picture point its instantaneous brightness.
In this system the whole number of surface elements of the screen
stays simultaneously excited without any interruption of their
appearance thereby suppressing the flicker and permitting a lower
scanning rate with a corresponding reduction of the frequency band
needed for the trans- mission of the picture signa!. Alike the
Mechau-projector the frames follow each other in continuous
superposition and progressive translucency along their succession.
This impression is aided by a special form of interlacing line
fields written down on the memory device. The picture is restored
by a tube having a mosaic-like UV lighted photocathode which
permits the loc al command of its emission to be projected on the
screen without geo- metrie distortion. The principle described fits
also for colour television. Resume L'auteur propose d'appliquer a
la synthese de l'image de television les effets optiques et
physiologiques du projecteur de cinema M echau.
