The displacement of a flexure hinge is analyzed by the two load types. One type is a simple model with one reactive force; and the other is a complex model with reactive force and reactive moment. The displacement error is evaluated by an experimental test. In the experiment, an image system is used to measure and inspect theoretical models of the flexure hinge. To improve the experimental error for displacement of the flexure hinge, I would investigate both the error propagation of the dimensional error and the horizontal-vertical alignment of camera.
