Abstract
An optical wireless communications system has a first optical wireless communications apparatus for transmitting a pilot beam and a second optical wireless communications apparatus for receiving the pilot beam to have a match for an optical axis of the first optical wireless communications apparatus and another optical axis of the second optical wireless communications apparatus. The first optical wireless communications apparatus has a modulator for modulating the pilot beam with a specific signal. The second optical wireless communications apparatus has a demodulator for demodulating the modulated and transmitted pilot beam to reproduce the specific signal and sending the reproduced specific signal to at least either the second optical wireless communications apparatus or an apparatus connected to the second optical wireless communications apparatus.
