摘要
Diameter of stationary carbon fibres is measured by diffraction of leaser beam. A condensing lens with position-sensitive photocell on radial arm is swivelled by stepper motor to scan the fringe maxima of the diffraction picture beyond 15 degree from laser axis, and computer calculates fibre diameter from distance of the maxima.
