Claim:
1. A method based on detecting the polarization property of a polarization maintaining fiber (PMF) probe for measuring structures of a micro part comprising: providing a PMF probe, which comprises a spherical tip and a PMF stylus; providing a probing system, which comprises the PMF probe, an optical path, a polarization demodulate unit and a signal processing unit; combining the probing system with a coordinate measuring instrument system to form an equipment based on detecting the polarization property of a PMF probe for measuring structures of a micro part, contact displacements of the spherical tip of the PMF probe and coordinates of the PMF probe relative to the coordinate measuring instrument system are acquired in real time and are processed by a measurement computer; fastening a micro part being measured to the measurement table of the equipment based on detecting the polarization property of a PMF probe for measuring structures of a micro part; obtaining coordinates of additional contact points and the structure geometry of a micro part being measured can be reconstructed from coordinates of the additional contact points.
