Abstract
The proliferation of digital imaging techniques has permeated in the Experimental Mechanics arena as well. More so the fact that since digital imaging records information in discrete and periodic intervals, this system lends itself nicely as a moire reference grating in the various moire techniques. The aliasing feature, which is generally avoided in traditional digital image and signal processing, now can be used to analyze the deformed specimen grating for deformation studies. This paper will discuss the use of digital moire techniques and demonstrate their application for the range of moire methods. Furthermore the use of phase shifting, one of the most powerful fringe processing technique will also be discussed in conjunction with this.
