Title:
SPATIAL LIGHT TRANSMISSION DEVICE AND SPATIAL LIGHT COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/203747
Kind Code:
A1
Abstract:
If a spatial light transmission device is configured to be suitable for large-capacity communication, the cost thereof increases. To solve this problem, this spatial light transmission device comprises: a plurality of laser beam sending means which respectively use light carrier waves not interfering with each other; a mode synthesis means which generates a synthesized laser beam obtained by converting laser signal beams respectively sent by the plurality of laser beam sending means into different modes and synthesizes the laser signal beams; and an emission means which emits the synthesized laser beam to free space.
