Claims12
An apparatus for measuring eccentricity of optical module, comprising:
- a rotating worktable including a movable supporting plate configured for supporting the optical module, the supporting plate being adjusted to a position such that the center of the optical module is directly above a center of the rotating worktable;
- a light source configured for emitting a cross-shaped light passing through the optical module;
- an image sensor device receiving a changeable cross image from the optical module;
- a driving device for driving rotation of the rotating worktable;
- and
- a processing device connected to the image sensor device, wherein the processing device is configured for analyzing the changeable cross image from the optical module, and thus obtaining an eccentricity of the optical module.
