Abstract
The invention relates to a method and a device for light modulation, wherein the intensity of light can be altered by means of electrically chargeable or charged particles (). The aim of the invention is to obtain light modulation in an economical, fast and reliably reproducible manner. According to the invention, a gas or vacuum is provided wherein the particles () can be displaced; a granular gas () is produced using said gas or vacuum between at least two electrodes () in such a manner that electrically charged particles () in the electric field between the electrodes () can be moved backwards and forth and the light which is to be modulated is guided through the granular gas () between the electrodes ().
