Paper Abstract

In the processing of fiber collimator packaging, the main factor that impacts the packaging quality is the optical coupling loss which aroused by the phase offset of optical fiber base pin inclined surface and grin lens inclined surface. Based on "detectable" and DFT, a new fiber collimator packaging method has been put forward. Using machine vision and digital image processing technology to make sure tips at correct phase, then the tips was inserted into the stainless steel sleeve and keep a feed motion to regulate the gap between the tips and grin lens. This way helps find the best packaging phase and makes sure the biggest output power. The system is composed of CCD camera, image acquisition card and VC++ image processing software. Experiments proved the effectiveness and practicality, the phase tolerance can be controlled in ± 3° and meet the fiber collimator packaging precision requirement. This packaging process have been used in practical production and it improved efficiency and qualified rate, it also has applied for the invent patent.
