| 摘要 |
The present invention, in the solar beam forming communication method using a solar light modulating device for communicating with a terminal through a solar optical modulation, comprising: a step of obtaining location information of the terminal; a step of receiving a digital signal comprised of a binary value from an outside; and a step of modulating a phase of an incident solar light concentrating in a direction corresponding to the location information of the terminal based on the binary value of the digital signal. Accordingly, the present invention can transmit a digital signal to a certain terminal by beam forming solar light entering through a solar light modulation. |
