Abstract: An optical inspection system includes at least one lighting module, a plurality of image-sensing units, and an editing and computing unit. Each lighting module is configured to generate a light beam for illuminating an object; each image-sensing unit is configured to capture an inspecting image of the object, wherein two adjacent inspecting images of the object has a repeated image; the editing and computing unit receiving the inspecting images captured by the image-sensing unit is configured to position the inspecting images in accordance with the repeated images and then recombinant the inspecting images for creating a full inspecting image.
