摘要： A method for growing a straight/non-tapered or a tapered high-transmission single-crystal fiber (SCF) using a fiber growth machine includes receiving, via an electronic control unit (ECU), a set of image data from a camera. The image data includes a first group of pixels of a feed fiber, a seed fiber, and a molten zone formed therebetween using a laser beam. The method includes identifying a feature of interest of the feed fiber, seed fiber, and/or molten zone within the first pixel group and locating position-identifying pixels within the feature of interest as a second pixel group. A horizontal position of the feed fiber is controlled via the ECU using the second pixel group while growing the fiber, including transmitting electronic control signals to actuators of the machine. An automated system for growing the SCF includes the camera configured and the ECU configured to perform the method.
