Abstract :
Discs of the ferroelectric ceramic p.l.z.t. have been used for electrically controlled light-beam deflection, with deflection angles up to 6°. and for mirrors of electrically variable focal length. The two techniques, both with nonvolatile memory, should find applications in optical instruments.
