摘要
The method and equipment are for measurement of circumference of rotating bodies, in partic. of rotating bodies with non round or irregular peripheries and are designed to produce exact measurement values with high measurement speed. The arc length differential produced for the body rim is integrated over an angle of 2 PI radians. The rim is scanned and electrical signals generated representing radius variations w.r.t. the corresp. angular position variation. These are differentiated and squared, then summed. The square root is then determined and the resulting signal integrated over the circumference. The periphery is scanned without contact using a laser method.
