WIRELESS OPTICAL LINK SYSTEM FOR VERY HIGH-SPEED DATA TRANSMISSION IN A ROAMING SITE

摘要

The invention relates to a system for immersing at least one first user (1) in a virtual or augmented reality, comprising an immersion space (2) in which said at least one first user (1) is able to move. According to the invention, the system comprises: - an optical reception device (11) worn by said first user, - processing means (3) comprising: - means for generating a first immersive multimedia stream intended for said first user (11) as a function of the movements of same, - means (TxO1, TxO2...TxOn) for optically transmitting a multiplexed optical signal (λ1, λ2...λn) to at least one optical access terminal (PAO), said optical access terminal (PAO) being arranged in said immersion space (2) in such a way as to form an optical cell (CEO) extending in said immersion space (2), said optical reception device (11) comprising a) means for receiving the multiplexed optical signal (λ1, λ2...λn) from said optical access terminal (PAO) via a wireless optical link when said first user (1) is located in the optical cell (CEO), and b) filtering means configured to extract the first immersive multimedia stream intended for the first user (1) from the multiplexed optical signal (λ1, λ2...λn)·
