Abstract:
An optical imaging arrangement includes an optical projection system, a support structure system and a control device. The optical projection system includes a group of optical elements supported by the support structure system and configured to transfer, in an exposure process using exposure light along an exposure light path, an image of a pattern of a mask onto a substrate. The group of optical elements includes a first optical element and a second optical element and the control device includes a sensor device and an active device. The sensor device is functionally associated to the first optical element and is configured to capture mechanical disturbance information representative of a mechanical disturbance acting on the first optical element in at least one degree of freedom up to all six degrees of freedom.

Claim (Index 16):
The method of  claim 15 , wherein:\n the control information comprises a previously established mechanical numerical model and a previously established optical model; the mechanical numerical model is a numerical model of a modeled part of the optical imaging arrangement, the modeled part comprising at least the first optical element, a capturing location at which the mechanical disturbance information is captured, and a disturbance path along which the mechanical disturbance propagates from the capturing location to the first optical element; the mechanical numerical model is representative of a geometric alteration in a position and/or an orientation and/or a geometry of the first optical element in response to the mechanical disturbance at the capturing location; the optical model is representative of an imaging error alteration of the imaging error based on the geometric alteration; the control device generates the correcting control signal based on the imaging error alteration, wherein the control device, in particular, uses previously established correcting control signal information stored in the memory and representative of the correcting control signal based on the imaging error alteration; and the control device: a) predicts an actual geometric alteration of the first optical element in response to an actual mechanical disturbance captured at the capturing location using the mechanical numerical model; b) predicts an actual imaging error alteration of the imaging error based on the predicted actual geometric alteration using the optical model; and c) generates an actual correcting control signal based on the predicted actual imaging error alteration using the correcting control signal information.
