Terahertz electronic control beam scanning optical link
2016
The invention provides a terahertz electronic control beam scanning optical link. The optical link comprises a beam scanning feed source system, a primary reflection surface and a focusing lens. The beam scanning feed source system is used for emitting a conical scanned terahertz wave beam with wave beam scanning characteristics. The primary reflection surface enables the conical scanned terahertz wave beam to be converted into terahertz wave beams which are distributed in parallel in a space, and then enables the terahertz wave beams to be reflected to the focusing lens. The focusing lens achieves the scanning and focusing of the terahertz wave beams. The optical link can quickly obtain the information of an imaging plane through the focusing scanning of the imaging plane, and can be applied in the fields of terahertz imaging, regional monitoring radars, lossless detection and target quick recognition and tracking.
