A SECURE OPTICAL WIRELESS COMMUNICATION LINK

Abstract: an optical wireless communication device () comprising: a data transmitter () configured to transmit an optical data signal; a masking transmitter () configured to transmit an optical masking signal; wherein the optical masking signal comprising a wavelength component substantially identical to a wavelength component of the optical data signal; the device () configured to set a certain distance (d) by controlling at least one of the data transmitter () and the masking transmitter (), such that a coverage area () of the optical data signal is overlapped with a coverage area () of the optical masking signal to a certain extent at the certain distance ( ) keeping a signal to noise ratio of the optical data signal below a threshold and complicating a recovery of the optical data signal by another device located at and beyond that certain distance (d).
