A computer vision based machine for automated packaging of photonics components

Three low-cost machines were designed and built under an ARPA-funded project to perform sub-micron alignments and attachments of single-mode fibers to different OE devices. These Automated Fiber Pigtailing Machines (AFPMs) are compatible with a manufacturing environment and have a modular design for standardization of parts and machine vision for maximum flexibility. The vision system greatly reduces mechanical fixturing constraints by requiring the critical components to be positioned only within the 1 mm field of view of the camera. Object-recognition algorithms allow the AFPM to quickly determine the initial locations of the OE device and the fiber and to position the fiber with sufficient accuracy for fine alignment via optical throughput maximization.
