|Abstract: ||The spacing between fringes is crucial for testing materials based on Moir´e technique.
In this work, the spacing between two consecutive bright (or dark) fringes, C , is
determined, for different grating separation , . The behavior shows that as the angle
between the gratings increases, the fringe spacing decreases. For gratings of 100
lines/mm and 300 lines/mm pitches adjusted parallel to each other, it is confirmed
that the fringe spacing equals 0.005000 mm. This is equal to the value for beat.
Moreover, a moir´e fringe projection technique applicable for deformation measurement
is done experimentally. The results show that moir´e fringe projection technique
is suitable for deformation analysis.|
