Abstract: A method and system of determining a z-distance between an optical fiber and a substrate are presented. The method can include, for instance: obtaining an image that includes an end of the optical fiber and a reflection of the end of the optical fiber from a surface of the substrate, and processing the image to determine a z-distance along a z-axis between the end of the optical fiber and the substrate.
