摘要： A method of testing a curved surface of a body, which can be used on bodies having only partial arcs available for testing and apparatus for performing the method comprising drawing a sensor over the surface of the body between two end points at which the relative angular orientation of the sensor and the body are known, and calculating from the information signals from the sensor, and from signals representing the relative angular orientation of the body and the sensor during the traverse, the parameters of a best fit limacon from which data indicating the eccentricity between the centre of the partial arc on the body with respect to the centre of relative rotation can be obtained and also a signal can be generated representing a reference figure against which surface variations of the body over the partial arc can be compared.
