发明名称 Coordinate measuring machine and a method for correcting non-linearities of the interferometers of a coordinate measuring machine
摘要 A method and a coordinate measuring machine (1) are provided, wherein the non-linearities of an interferometer (24) can be corrected. A measuring stage (20) traversable in a plane (25a) is provided for measurement. The substrate (2) is placed in a measuring stage (20); wherein the position of the measuring stage (20) along each of the motion axes is determined by at least one interferometer (24) in each case. A computer (16) is provided for compensating the non-linearity inherent in each of the interferometers (24), wherein the position of the measuring stage (20) to be determined by the interferometers (24) is arranged along a trajectory (52, 60, 67) of the measuring stage (20), which is composed at least partially of components of the axes.
