A method for providing corrections of distortions of an imaging device. Initial corrections may be provided through the use of active optics, to apply forces to the imaging device, or to a compensator device in a common optical path with the imaging device, so as to introduce deformations that cancel out the distortions. This action, in turn, may induce undesirable, secondary aberrations. The method of the invention provides steps for identifying, isolating and removing the undesirable secondary aberrations, and computing new applied forces that cannot induce the secondary aberrations.

Method for correction of distortions of an imaging device

A method for providing corrections of distortions of a mirror. Initial corrections may be provided through the use of active optics, to apply forces to the mirror to introduce deformations that cancel out the distortions. This action, in turn, may induce undesirable aberrations. The method of the invention provides steps for identifying, isolating and removing the induced undesirable aberrations, and computing new applied forces that cannot induce the undesirable aberrations.
