Alignment system and method for calibrating position of optical fiber bore ferrule

Abstract

The present invention discloses an alignment system for calibrating a position of an optical fiber () in a bore () of a ferrule (), comprising: a calibration ferrule () having an alignment guide hole () formed therein; an alignment guide element () for calibrating a center position of a guide hole () of the ferrule, so that a center of the guide hole () of the ferrule () is aligned with a center of the alignment guide hole (); a fiber core alignment element () comprising a fiber core () having a center positioned at a theoretical center relative to a positioning reference defined by the center of the alignment guide hole (); an optical vision system for identifying a center position of a fiber core () of the optical fiber () and the center position of the fiber core () of the respective fiber core alignment element (); and a controlling and moving system for actively adjusting the position of the optical fiber () in the bore () of the ferrule () under the guide of the optical vision system, so that the center of the fiber core () of the optical fiber () is aligned with the center of the fiber core () of the respective fiber core alignment element (), and so that the center of the fiber core () of the optical fiber () is positioned at a theoretical center relative to a positioning reference defined by the center of the guide hole () of the ferrule ().
