Abstract

The present invention provides for a Line of Sight (LOS) electromagnetic beam (EM) detection system configured with an enclosure, a detection device, a processing device, a storage device, and a communication device. The enclosure may or may not be electromagnetically shielded from the surrounding environment. The enclosure may contain one or more detection devices and one or more portals configured for a user to look through. The detection devices may be a non-contacting, active-dry electroencephalogram (EEG) electrode or a high input impedance EEG electrode. The processing device may be a specifically programmed general purpose computer. The communication device may be auditory and/or visual. The storage device may store signals from the detection device for later analysis and statistical manipulation. In some embodiments, the LOS detection system may be used as a switch responding to interaction with a LOS beam emanating from an ocular cavity.
