Abstract: An automated optical double-sided inspection apparatus includes a first image-capturing portion, a second image-capturing portion, a platform, a first light-blocking portion, a second light-blocking portion, and a processing portion. The platform carries an external object. When the processing portion operates in a first capturing mode, the second light-blocking portion blocks visible light from passing therethrough, while the first light-blocking portion allows visible light to pass therethrough, so that the first image-capturing portion shoots a first side of the external object through the first light-blocking portion to obtain a first image. When the processing portion operates in a second capturing mode, the first light-blocking portion blocks visible light from passing therethrough, while the second light-blocking portion allows visible light to pass therethrough, so that the second image-capturing portion shoots a second side of the external object through the second light-blocking portion to obtain a second image.
