# Gauge for measuring a cross-sectional dimension deviation on an elongate object

## Abstract

An apparatus and method for measuring a cross-sectional dimension or deviation from a predetermined shape of an elongated moving object. The apparatus is rotated about the object and includes a light source and photo-diode array. By continuous rotation of the apparatus about the object, deviations in the cross-sectional dimension are determined.
