We focus on resolving the following problems in FTP, that is how to guarantee the measurement accuracy of FTP when the connect line between the exit pupil of the projecting lens and that of the entrance pupil of the imaging lens is not parallel to the reference, or the two pupils are not coplanar, or neither the connect line parallel to the reference nor the two pupils coplanar.
