Zapewnienie możliwości realizacji kanału zwrotnego w systemach VLC stanowi obecnie jeden z podstawowych problemów, który musi zostać rozwiązany, aby technologia ta mogła w przyszłości konkurować z systemami radiowej transmisji danych. Przedstawiono wyniki badań weryfikujących potencjalną możliwość wykorzystania diod świecących LED w roli fotodetektorów. Podejście to otwiera nowe możliwości w odniesieniu do tworzenia kanałów transmisji w systemach VLC. Przeprowadzone badania potwierdzają, że przynajmniej część diod świecących LED może pełnić taką rolę, jeżeli tylko zostaną odpowiednio spolaryzowane.

Ensuring of feasibility the realization of feedback channel at the VLC systems, is currently, one of the key problems that must be solved, if we want believe in that this technology will got a real chance to compete with the data transmission radio systems in the future. Today, it's very difficult to predict, which of the proposed solutions in this regard eventually reaches a dominant position at the end. Perhaps, some of them will be operate in parallel. The paper presents the results of a verifying the potential possibility of using for this purpose the LEDs as photodetectors. This approach opens new possibilities in respect to create transmission channels at the VLC systems in very flexible way. The carried out studies confirm that at least some LEDs can act as photodetectors, if they are appropriately polarized only. The article is an extension of the work [1].
