1.3 GENERAL FEATURES OF THE FTM
It should be noted that the application of the FTM is not restricted to the
2-D spatial fringe pattern but includes a general multidimensional spatio-
temporal fringe signal g(x, y, z;t) with a spatiotemporal carrier frequency

. e advantage of introducing a multidi-
mensional spatial carrier frequency vector was rst pointed out by Bone
et al. [17], who demonstrated with a 2-D interferogram that aliasing errors
caused by undersampling can be avoided by an appropriate choice of the
direction of the 2-D carrier frequency vector. Shown in Figure ...
