An electro-optical instrument to gauge automotive rear axle shafts is described. A high contrast image of the axle lug flange is projected via a high quality photographic lens on two self-scanning linear photodiode arrays. In one three-second rotation, a dedicated digital processor measures bolt circle location, hole diameter and separation. The unit automatically: compares each measurement with preset tolerances, computes the average bolt circle diameter, computes the bolt circle runout, makes a pass/fail decision, provides a digital readout, marks the axle shaft with colored ink and provides the operator a pass/fail light.
