Abstract
This invention relates to a method for controlling a light output signal emitted by a set of light sources comprising at least one light source, wherein said light output signal comprises a modulation signal which carries individual information, the method comprising recurrently: remotely detecting the light output signal of said set of light sources; determining at least one quality measure of said remote detection of the light output signal; and adjusting the modulation signal on basis of said at least one quality measure.
