Abstract: The invention relates to the display of visible images corresponding to patterns projected by means of ionizing agents such as X-rays, gamma -rays or particle beams. The image converter in accordance with the invention comprises: a fluorescent screen optically coupled to a photoconductive film, the latter being electrically coupled to a liquid crystal film whose dynamic scattering properties are utilised to render visible the patterns projected onto the fluorescent screen by means of the ionizing radiation.

Abstract: The present invention relates to electro-optical modulators wherein dynamic scattering of a layer of liquid crystal is controlled for transmitting a variable amount of radiant energy. The liquid crystal modulator according to the invention comprises a cell associated with an a.c. generator. Under the action of this generator the delay time of the cell is reduced without introducing any misalignment of the liquid crystal molecules in the absence of an electrical control signal.
