The invention provides a deformed
secondary mirror based on a piezoelectric driver, which comprises a mirror face, a driver and a rigid base, wherein the mirror face, the driver and the rigid base are bonded with each other into a
whole body; the mirror face is in the structure of shell, the front side of the mirror face is an aspheric face and is simultaneously taken as the mirror face of the deformed mirror and the
secondary mirror of a
telescope, the back side of the mirror face is a spherical face, and the
lower face of the mirror face is provided with an
electrode head which is integrated with the mirror face, thereby increasing the distance between a bonding face and the mirror face and reducing the local deformation burning bonding; the two ends of the driver are respectively bonded and matched with an interface, thereby guaranteeing the compact contact among the driver, the back face of the mirror face, the bottom face of the
electrode head and the top face of the base, guaranteeing the orientation of the driver, and reducing the local deformation during bonding; and the top face of the rigid base is the spherical face, thereby guaranteeing the supporting condition of the driver and realizing the lightweight on the premise that the rigidity is guaranteed. The mirror face of the deformed
secondary mirror, the driver and the rigid base are bonded with each other in to a
whole body, therefore, compared with the existing deformed secondary mirror, the deformed secondary mirror has the characteristics of compact structure, high rigidity, good stability, high reliability and small weight, and is applied to the application field of the deformed secondary mirror with the less amount of driving units.
