Paper Abstract

We present a system fitted for digitizing pictures coming from high speed cinematography systems as well as pulsed radiography. The system is built around a slow scanning television tube which provides a resolution of 1024 x 1024 -512 x 512 or 256 x 256 pixels coded on 256 levels assigned to an adjustable range of optical density. The size of pictures or X rays images may vary from 24 x 24mm2 up to 400 x 400 mm2. Geometrical distorsion ra-te is better than 10-3 and photometrical error about 2 x 10-3 after processing. The reading noise added to the picture is equivalent to 0.7 x 10-2 D.
