An improved structure and method for building large-aperture lightweight deformable mirrors uses a hinged substrate. In addition to reduced weight, the approach provides rigidity to the mirror, which is necessary for the accurate response to actuator commands and tolerance to disturbances. No stresses...http://www.google.fr/patents/US6984049?utm_source=gb-gplus-shareBrevet US6984049 - Hinged substrate for large-aperture, lightweight, deformable mirrors
