METHODS FOR OPTIMIZING GRADED INDEX FIBER LENGTH TO IMPROVE IMAGE QUALITY

In some implementations, a fiber processing machine may receive an optical assembly comprising an input fiber, an output fiber, and a graded index fiber spliced between the input fiber and the output fiber, wherein the graded index fiber has a pitch length and a processed length. A light source may deliver input light into an input end of the input fiber while one or more components monitor output light at an output end of the output fiber. The fiber processing machine may alter a core diameter and the processed length of the graded index fiber until one or more measurements of the output light at the output end of the output fiber indicate that the output light is a perfect image of the input light.
