Abstract:
A method for evaluating the optical insertion loss of a mechanical splice joint of two optical fibers with a laser source includes, upon initiation by a user, automatically performing the steps of: checking for ambient light, estimating the level of noise by analyzing an area of a sensor that is not illuminated by external sources and setting a noise threshold, checking self-alignment by taking a foreground image of the joint with the laser source turned on and one with it turned off, subtracting the images to obtain a resultant image, setting all pixels with levels below the noise threshold to zero, selecting a region of interest of the joint, computing a centroid and a width of the resultant image based on the region of interest, estimating a tilt and if the tilt is above a certain threshold, compensating for the tilt, and processing the resultant image.
