Project Overview

The client uses two machines to obtain high resolution optical coherence tomography images to diagnose conditions like macular degeneration. In the case that patients are not able to follow directions to move their eyes a certain way, the machines are bulky and difficult to maneuver. This hampers ability to obtain the necessary data. The goal is to create a motion stage that will allow the operator to move the machine in a very refined way that will allow him or her to precisely position the machine for good data acquisition.
