Transfer optics

摘要

A transfer optic mirror thin enough to permit small influence functions for surface changes is made from cynate ester composites. The thin mirror resulting is then shaped by a plurality of piezolectric actuators connectors to push/pull rods spread evenly over the back surface of the thin mirror a distance determined by the mirror's influence function. The mirror is held by a support with the same coefficient of expansion as the mirror so external heating and cooling does not distort the mirror. The actuators are connected to a computer so each is separately controlled to contour the mirror as desired.
