Abstract (in Japanese) (See Japanese page) 
(in English) We are researching a system to transmit live images and information such as photographing instructions in both directions. We have proposed a method to modulate received light for video transports with this information, and send it back to the transmitting side. We conducted a basic experiment using a speech prompter to verify the principle of sending back this information in the QR code format while transmitting video by FM. This paper focuses on the circuit which guarantees the deep optical modulation by the wide band radio waves for the LED which radiates the almost parallel beam.
