| dc.description.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 | en_US |
