Measurement of Core Position of Fiber Array by a Calibrated Mask Method
A method for obtaining the core positions of fiber array is described. The technique is based on the use of calibrated mask. Because the mask and the fiber array are simultaneously moved and imaged, the measuring system is relatively simple in image processing, location, and vibration isolation. A prototype system with common components has been built for testing a number of commercial fiber arrays.
