Abstract
A telecentric imaging system includes a Fresnel lens mountable in proximity to an object to be imaged, a source of light for illuminating the object, and an aperture stop located at least in the telecentric imaging system is incorporated into an optical inspection machine which permits optical distortion produced by the telecentric imaging system to be corrected using a look-up table.
