Abstract: An automated optical measurement system and method for a near eye display are provided. A controller first controls the near eye display to display a specific pattern, then controls a displacement generation module to drive an image sensing module toward or away from an imaging module, and controls the image sensing module to capture the specific pattern to obtain focus images; and the controller performs focusing according to the focus images. Finally, the controller measures an optical characteristic of the near eye display. Accordingly, the focusing method used is to capture the specific pattern displayed by the near eye display while moving the image sensing module, and perform automatic focusing by comparing the capture results.
