Abstract
A system includes a first communications unit, e.g., a transmitter, and a second communications unit, e.g., a receiver. The first communications unit has a controllable illumination device, which emits light modulated according to a predefined data flow, and the second communications unit has a camera, including an optical element and an image sensor. A light-sensitive surface of the image sensor has a plurality of lines of light-sensitive elements, and the image sensor is arranged such that the image of the illumination device projected onto the light-sensitive surface of the image sensor by the optical element is unsharply imaged and/or covers more than half of the light-sensitive surface and is scanned line by line, e.g., so that the image has stripes of different brightness and/or that the brightness profile induced transversely to the line direction spatially indicates the time characteristic of the data flow.
