    摘要: The invention provides a method for determining vibration-related information by projecting an aerial image at an image position in a projection plane, mapping an intensity of the aerial image into an image map, the image map arranged for comprising values of coordinates of sampling locations and of the intensity sampled at each sampling location, and measuring intensity of the aerial image received through a slot pattern. The method further includes determining from the image map a detection position of a slope portion of the image map, at the detection position of the slope portion, measuring of a temporal intensity of the aerial image and measuring of relative positions of the slot pattern and the image position, the relative positions of the slot being measured as position-related data of the slot pattern and determining from the temporal intensity of the aerial image vibration-related information for said aerial image.

    摘要: A lithographic apparatus is arranged to project a patterned radiation beam from a patterning device onto a substrate using a projection system. The lithographic apparatus comprises: an interferometric sensor for measuring the wavefront of the radiation beam at the level of the substrate, the interferometric sensor having a detector; an actuator for displacing the interferometric sensor in a direction along the optical axis; a first module for determining the change of phase of the wavefront at each of a plurality of locations on the detector of the interferometric sensor, the change of phase resulting from displacement of the interferometric sensor by the actuator between a first position and a second position; and a second module for determining, for each of the plurality of locations on the detector, the corresponding pupil location at the pupil plane of the projection system traversed by the radiation, using the change of phase determined by the first module and the value of the displacement of the interferometric sensor by the actuator, to produce a mapping between locations on the detector and corresponding pupil locations. Once the mapping has been obtained, the numerical aperture and telecentricity of the projection system can be measured.
