摘要:
A micromirror of a micromirror array in an illumination system of a microlithographic projection exposure apparatus can be tilted through a respective tilt angle about two tilt axes. The micromirror is assigned three actuators which can respectively be driven by control signals in order to tilt the micromirror about the two tilt axes. Two control variables are specified, each of which is assigned to one tilt axis and which are both assigned to unperturbed tilt angles. For any desired combinations of the two control variables, as a function of the two control variables, one of the three actuators is selected and its control signal is set to a constant value, in particular zero. The control signals are determined so that, when the control signals are applied to the other two actuators, the micromirror adopts the unperturbed tilt angles as a function of the two control variables.

Measuring an aerial image with an aerial image measuring device having a light detector and a light blocking layer for separating polarization components of light incident thereon. The light blocking layer has first and second apertures structured differently from each other, wherein the different structures transmit at least one of the polarization components differently. The detector provides separate samples for light transmitted through the first and second apertures. Separate image profiles for each polarization component of the aerial image are generated using the samples provided by the detector. Image recovery for each of the generated image profiles is performed to generate estimated image profiles for each polarization component of the aerial image that exclude the effects of transmission through the first and second apertures of the aerial image measuring device.
