Abstract
A pivoted platform has two flexible arms having rigid end zones which are attached by means of spacers to piezoelectric elements. The piezoelectric elements are made to deflect in opposite directions upon the application of the electrical signal to cause the platform to pivot. Applying voltages of the opposite polarity causes the platform to pivot in the opposite direction. A mirror may be attached to the platform to produce a scanning mirror for the vertical deflection of a television image.
