Abstract
A method and apparatus for laser marking a moving workpiece such as a wire or cable directs a substantially constant rapidly pulsed laser beam at a frequency of at least 15 Hz towards a low inertia, low mass rotatable mask with character apertures disposed around its periphery. The mask is driven asynchronously to present successive characters with each pulse to form a composite image.
