Abstract
A digital optical comparator has a holder for a part under study. A light source illuminates the part and casts an Image of the part onto a camera, which is provided with a lens. The Image captured by the camera is displayed on a screen, and a drawing of the part is overlaid on the image of the part. Thus, defects in manufacturing can be easily and readily identified. In addition, a determination of whether the part is manufactured within tolerances can also be visually determined.
