Abstract
Equal and opposite moments are applied to distort a specimen in varying the configuration thereof so that transfer of reaction forces into the specimen's supporting structure is avoided. Specific embodiments where the specimen is a mirror in an optical system are disclosed.
Claims6
Apparatus for controlled multiple mode distortion of an electromagnetic radiation element, comprising:
- at least three posts affixed to the electromagnetic radiation element and extending therefrom;
- and
- actuators disposed between said posts for applying variable force therebetween, equal and opposite moments being developed from the force of each said actuator through said posts to distort the electromagnetic radiation element, said posts being located on the electromagnetic radiation element to provide at least two modes of distortion therein.
