FIELD: physics; optics.
SUBSTANCE: invention relates to creation of images for data transmission and may be used in city advertising and modifiable information messages. Device comprises optical fibers, light generator and optically transparent plate. Optical fibers are connected to rear side of the plate. The plate is covered with renewable film information medium, which is coated with optically transparent material. Optical radiation from light generator is supplied to opposite ends of optical fibers by means of fiber-optic cable. Device may be floor- or wall-mounted indoors or embedded into pavement.
EFFECT: advanced design of information medium and facilitation of its use.
