Abstract

A random-access beam scanner using axial-mode expansion of a stack of piezoelectric disks has been fabricated and tested. The measured performance was comparable to that of scanners using galvanometer or piezoelectric bimorph drivers. Computations predict that improved coupling of the stress developed by axial-mode devices can extend the performance of these devices to levels well beyond those now available.
