Abstract
The invention relates to a bimorph optical device comprising a deformable optical element and active elements made of piezoelectric ceramic provided with electrodes, said elements being controlled in pairs and in opposition so as to produce a compression movement for a first element of a pair and an extension movement for the second element of a pair, the device being characterized in that the optical element () presents an optically active first main surface () and a second main surface () opposite to the first main surface, together with at least first and second opposite lateral faces (), and in that the ceramic active elements comprise at least two pairs of bars () of piezoelectric ceramic placed facing each other on said first and second lateral faces (), each pair comprising two bars () placed on one of the first and second lateral faces () on either side of a middle surface of the optical element () that constitutes the neutral axis thereof.
