Abstract

Acousto-optic techniques for the generation of spot matrix alphanumerics on continuously moving target material are described. The systems utilise a high p.r.f. Nd:YAG laser to mark the characters point by point. Two approaches are considered: a simple system using a single acousto-optic deflector is briefly discussed which relies on the movement of the target material to provide the necessary shift in the orthogonal direction; and a two axis system is described which enables a high utilisation of the available laser pulses, resulting in a high throughput rate of the marked target material.
