Abstract
A camera based positioner (CBP) for near-field measurement and a method therefor, and a near-field measurement system are provided. A measurement probe and an antenna under test (AUT) are automatically aligned to a position for near-field antenna measurement by recognizing a position and a rotation angle of the AUT based on an interval and an angle between neighboring laser sources represented in an image taken by emitting laser beams from at least two laser sources located with a predetermined interval and a predetermined angle.
