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.
Claims21
A directed energy beam virtual fence, comprising:
- a source unit to provide an energy beam
- a sequence of relay units disposed at intervals along a length of the virtual fence
- wherein each relay unit in the sequence
- receives the energy beam from a previous unit
- recollimates the energy beam
- directs the recollimated energy beam towards a subsequent unit.
A directed energy beam virtual fence comprising:
- a sequence of units, the sequence starting with a source unit and continuing with a plurality of relay units
- the source unit providing an energy beam to a first relay unit
- each relay unit
- receiving the energy beam from a previous unit in the sequence
- recollimating the energy beam
- redirecting the recollimated energy beam towards a subsequent unit in the sequence
- wherein the energy beam has a beam power density sufficient to deter an intruder from crossing the virtual fence.
A directed energy beam virtual fence comprising:
- means for generating an energy beam having a beam power density sufficient to deter an intruder from crossing the virtual fence
- plural means for recollimating and redirecting the energy beam disposed at intervals along a length of the virtual fence.
A method of deterring intruders from crossing a boundary, comprising:
- generating a high power millimeter-wave energy beam, the energy beam propagating along a sequence of linear segments, wherein the sequence of linear segments approximates the boundary.
