Abstract
A free space optics system includes a transmitter for generating an orbital angular mode (OAM) laser signal and a receiver. The OAM laser signal may be a Multiplexed Laguerre Gaussian (Mux-LG) OAM laser signal. The receiver includes a beam splitter for receiving the OAM laser signal and a charge coupled device (CCD) camera for receiving the OAM laser signal from the beam splitter and imaging the OAM laser signal. The receiver further includes a computing device in communication with the CCD camera. 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. The computing device may detect the interception using a deep learning model or a convolutional neural network (CNN).
