Deformable mirror (DM) is an active element that can change the shape of the surface to compensate for wavefront aberrations. Historically, the development of DMs started from piezostack deformable mirrors (PDM) due to their large stroke, flexibility

We have studied the effect of the mechanical activation of the starting oxide mixture on the particle size of the resulting powders and the microstructure of electrostrictive lead magnesium niobate-lead titanate ceramics. The results demonstrate that

The introduction of tungsten and niobium oxides into pure bismuth titanate allows one to reduce dielectric losses and the conductivity down to 10−10 S/m, to raise the permittivity up to 170, and to stabilize piezoelectric properties. The thermos le
