This work deals with the development of a full-field measurement method of plane strain at the micrometric scale. The kinematic measurement is done thanks to the so called « grid method » that analyzes the deformation of a periodic pattern deposited onto the surface to study. To produce gratings, the direct interferential photolithography is used. To observe and digitize these gratings, the choice has been to use a white-light interferometric microscope which allows to get the 3D topography of the surface of interest. A noise study has been carried out in order to optimize the making of gratings regarding their mechanical application. Moreover, the application of rigid body motions has pointed a spatial correlation of the noise that cannot ...
