Paper Abstract
Method of computer digital image processing was utilized to measure non-circularity of single mode fiber. The two end
faces were polished, the faces come into plane, and which are perpendicular to fiber axis. Laser beam was thrown on one
end of the fiber, and an inerratic spot was formed from light beam put out at another end of the fiber. The spot was shot
by a digital camera with 5.1x106 pixels. The image was processed with a computer. The process includes full color
picture being translated into gray one, contrast enhancement, median filtering, and picking-up contour line. The every
different three points on the contour line were taken out to determine one circular radius, average of many radiuses was
calculated, The maximum radius and the minimum radius are picked out to calculate the fiber no-circularity in according
to definition. Visual C++ and Matlab were used to programme. The results of experiment show that measurement
precision is independent of the sampling number, but dependence of gray value, and average standard deviation is about
0.03%.
