Description

technical field [0001] The invention relates to the technical field of wireless high-speed laser communication, in particular to an ultra-high-speed wireless optical communication device oriented between an aerospace platform cabin and a load cabin. Background technique [0002] In recent years, the strategic position of aerospace has become more and more important, and human exploration of the universe has been increasing. Due to the hyperspectral and high spatial resolution of existing payloads such as space cameras, a large number of high-pixel images or high-definition videos will be generated per unit time of the payload. For this reason, there is an urgent need for real-time transmission of massive data in the payload cabin (hundreds of gigabits per unit time). Second, or even higher), at the same time, existing space payloads often have multiple payloads working together, and adapting to multi-load data transmission is also one of the development trends. The current ...
