Method of making standard electrodisplacive transducers for deformable mirrors

摘要

A construction for electrodisplacive transducers for use in deformable mirrors in which the transducer is assembled from two or more segments of electrodisplacive material. Each segment contains multiple stacked layers of electrodisplacive material which are separated from adjacent layers by electrodes. During manufacture the segments may be individually tested and sorted by the stroke that they produce for a given electrical input signal applied to the stacked layers. Segments are selected and fastened to each other so that the total stroke produced by the selected segments equals the stroke required from the actuator.
