Error Budgeting & Imaging Using Micro-Scale AFM
1. Overview
This is a final project for Advanced Mechatronic II. Using a tapping mode macro-AFM which can track a sample in a vertical (z) position and moving stage in a horizontal (x-y) plane, an object can be sampled to acquire an image. This project involves error modeling for the imaging stages and experiments that aims to scan over a nickel coin using LabVIEW, a programmable moving stage, and macro-AFM.
