Abstract
Luminosity values of a structure carrying information, in particular grey scale values, are transformed into corresponding isochromates. The transformation is effected by optically imaging the information carrying structure onto a layer of liquid crystals. By this means, a thermogram corresponding to the information carrying structure produced in the layer of liquid crystals, so that the luminosity values of the structure carrying information is transformed into isotherms in the layer of liquid crystals, and the isotherms are converted into isochromates as a result of the colour/temperature behaviour of the layer of liquid crystals.
