An optical inspection apparatus includes a projection optical system, a digital microscope system, and a calculating unit electrically connected to the projection optical system and the digital microscope system. The projection optical system is configured to obtain an inclined projection image of multiple through hole structures in a substrate. The digital microscope system is configured to obtain a 2D interference image. The calculating unit is electrically connected to the projection optical system and the digital microscope system. The calculating unit is configured to analyze the 2D interference image to obtain a stereoscope image data and to analyze the inclined projection image to obtain multiple parameters of the through hole structures. The optical inspection apparatus can be used to get a feedback in real-time. Multiple through hole structures can be inspected at the same time such that the time required to scan the substrate is reduced.
