Abstract
A curve tracer comprising: an optical tracer head for scanning a line having at least a substantial transverse component and at least one marking on the line, with a predetermined scanning speed. The head is moved along the line at a speed substantially lower than the scanning speed. There is a control unit for controlling the movement including an integrator, means for feeding the integrator with a voltage proportional to the speed of the tracer head, and means for supplying a signal proportional to the distance travelled by the tracer head when the head moves over the marking.
