For automated inspection, 100% inspection is desirable from the viewpoint of quality assurance, and in recent years, the introduction of image sensors has been progressing. Here, we will introduce the basic knowledge of image sensors, advantages and disadvantages, differences from dedicated inspection devices, how to select peripheral devices such as lenses and lighting that accompany image sensors, and the advantages of automated optical inspection.

In the automated optical inspection, the work recognized by the eyes is compared with the free sample and considered by the brain to judge the quality. The image processing system and image sensor replace the human eyes with a camera and the brain with a controller. The image sensor processes the data captured...
