Document Type and Number:
WIPO Patent Application WO/2024/057676
Kind Code:
A1
Abstract:
[Problem] To provide a high-speed optical wireless communication system. [Solution] This optical wireless communication system (1000) comprises a transmission device (100) and a reception device (200). The transmission device comprises: a signal conversion unit (101) that converts communication data to an optical signal; and a light source (102) that emits near infrared light corresponding to the optical signal. The reception device comprises an optical detection unit (300) that receives the near infrared light. The optical detection unit comprises: an imaging optical system (301); an imaging element (303) including a plurality of two-dimensionally arranged opto-electric conversion units (311); and a filter (302) that limits the wavelength range of light incident upon the imaging element. The plurality of opto-electric conversion units each are an avalanche diode.
