摘要： The invention relates to a bidirectional wireless communication device which is based on the use of light, including at least: (a) one or more emitting modules (10), each emitting module (10) being made up of: a light source (9) powered by a control means (6) and emitting amplitude- and/or phase-modulated light (1); a control means (6) which generates an electrical signal from the digital-to-analog conversion of the source data (2) to be transmitted; (b) a receiving module (20) made up of: a photodetector (11) illuminated by said modulated light (1) and generating a modulated electrical signal (14, 15) in response to said modulated light (1); and a processing module (12) for processing the signal generated by said photodetector (11), capable of communicating with the control means (6) via the backward channel (17). Said wireless communication device is characterised in that the receiving module (20) also includes an electronic means (13) positioned between the photodetector (11) and the signal-processing module (12) and capable of matching the impedance of the photodetector (11) such as to maximise the signal-to-noise ratio of the modulated electrical signal (14) by minimising the distortions of said modulated electronic signal (14) associated with incorrect impedance matching at the output of the photodetector (11), while maximising the level of the modulated electrical signal (14) and the throughput of transmitted data (18).
