Abstract : This report presents the evaluation results of the performance of a bimorph piezoelectric mirror supplied by the International Laser Center. The first part describes the spatial modes of the mirror, their linearity, hysteresis and their temperature dependence. The next part describes the dynamic behaviour. The final part of the report presents results of the performance of a simple adaptive optical system for imaging through laboratory generated turbulence. Tbe mirror and system might be suitable for low order correction in a 1m - class telescope. (jg)
