  • Method and Apparatus for Determining Topography of an Object
    Publication number: 20110252891
    Abstract: A method for determining the topography of a static surface (305) of an object (301) comprises the steps of: (a) selecting a region (301a) on the static surface (305) of the object (301); (b) directing an incident monochromatic electromagnetic wave (302) onto the region (301a) while the surface (305) and the incident monochromatic electromagnetic wave (302) are moved relative to one another, the incident monochromatic electromagnetic wave (302) being characterised by a frequency f0, an amplitude A0 and a propagation direction, the direction of movement (304) being substantially not parallel to the propagation direction of the incident monochromatic electromagnetic wave (302), wherein the surface (305) reflects the incident monochromatic electromagnetic wave (302) thus generating a reflected monochromatic electromagnetic wave (303), the movement (304) being characterized by a movement frequency (F) and a movement amplitude (A); (c) determining properties of the monochromatic electromagnetic wave (303) reflecte
