    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 metrology device for inspecting a substrate is provided. In an embodiment, the metrology device includes a remote radiation source device, an optical system for creating a radiation beam, and an optical fibre for transferring radiation from the optical system to the location where the metrology operations are performed. The optical system includes a control system that includes a deformable mirror, a detector that detects the position of a radiation beam, and a controller that produces a control signal for input into the deformable mirror, the control signal being based on the detected position of the radiation. In this way, the shape of the deformable mirror can be used to control the position of the radiation beam output by the optical system into the optical fibre.
