Abstract
A scanning probe is provided for use with a coordinate measuring machine. The scanning probe includes a rotary position detection configuration which outputs X and Y position signals indicative of a rotation of a stylus coupling portion about a rotation center, and an axial position detection configuration which outputs a Z position signal indicative of the position of the stylus coupling portion along the axial direction. The Z position signal is substantially insensitive to motion of the axial detection deflector in at least one direction that is transverse to the axial direction. The X, Y and Z position signals may be processed to determine a 3D position of a contact portion of the stylus, which may include utilizing the Z position signal in combination with known trigonometry of the scanning probe to remove axial motion cross coupling components from the X and Y position signals.
