Title:
SPATIAL OPTICAL COMMUNICATION RECEIVER
Document Type and Number:
WIPO Patent Application WO/2019/167237
Kind Code:
A1
Abstract:
An optical signal from a pointing mirror (102) is condensed by a condensing optical system (103). The condensed optical signal is transferred through a multicore fiber (104). The transferred optical signal is coherently detected by a coherent detector (108) and decoded by a digital signal processing unit (110). The digital signal processing unit (110) detects an angular deviation of the optical signal input to the condensing optical system (103). The pointing mirror (102) updates a compensation angle in correspondence to the angular deviation detected by the digital signal processing unit (110).
