Abstract
Apparatus and techniques for automated optical inspection (AOI) utilizing image scanning modules with multiple objectives for each camera are provided. A scanning mechanism includes optical components to sequentially steer optical signals from each of the multiple objectives to the corresponding camera.
Claims20
A system for illuminating an article, comprising:
- at least one light source;
- a plurality of objective modules arranged to have fields of view covering a portion of the article;
- and
- a selection mirror mechanism movable to sequentially direct light from the light source to a first one of the objective modules and then to at least a second one of the objective modules such that the fields of view are illuminated.

A system for illuminating an article, comprising:
- at least one light source;
- a plurality of objective modules arranged in an arc to have fields of view covering a portion of the article;
- and
- a selection mirror mechanism movable to sequentially direct light from the light source to a first one of the objective modules and then to at least a second one of the objective modules such that the fields of view are illuminated.
1 more element
A method for illuminating an article, comprising:
- bringing at least a portion of the article in fields of view of a plurality of objective modules;
- and
- adjusting a selection mirror mechanism to sequentially direct light from a light source to a first one of the objective modules and then to at least a second one of the objective modules such that the fields of view are sequentially illuminated.
