1. A free space optics system, comprising:
a transmitter for generating an orbital angular mode (OAM) laser signal; and
a receiver comprising:
a beam splitter for receiving the OAM laser signal;
a charge coupled device (CCD) camera for receiving the OAM laser signal from the beam splitter and imaging the OAM laser signal; and
a computing device in communication with the CCD camera, wherein the computing device is configured to determine a power of the OAM laser signal from images taken by the CCD camera to detect interception of the OAM laser signal.
