ABSTRACT:
An optical scanner capable of scanning parallel to two intersecting axes. The scanner comprises a single electromechanical transducer and a compliant link interconnecting the transducer with an optical element to which the two-axis movement is to be imparted. The link is selectively compliant to two planes containing the two axes and it is oriented to receive from the transducer force components in both planes. The transducer is driven at the frequencies of the resonances associated with the link compliances and the masses involved therewith. The link thereby imparts amplified motion to the optical element simultaneously in both planes, the resulting path described by the element thus being a Lisssajous pattern.
