Abstract
A receiver device for communication via modulated light transmission, intended to be coupled to a terminal which uses data received via modulated light, is disclosed. The receiver device includes at least one trough, said trough comprising: a slot for receiving at least one light ray of the modulated light, and a first guiding surface, coupled to the slot, said slot being arranged at the entrance to the first guiding surface, the first guiding surface comprising at least one internal surface which is reflective and shaped to guide the light ray by successive reflections to at least one photoreceiver coupled to the receiver device.
