ABSTRACT:
There is disclosed apparatus and methods for a directed energy beam virtual fence. The directed energy beam virtual fence may include a source unit to provide an energy beam and a sequence of relay units disposed at intervals along the length of the virtual fence. Each relay unit in the sequence may receive the energy beam from a previous unit and may recollimate and redirect the energy beam towards a subsequent unit.
