Abstract Using the properties that electrorheological fluid can form periodic chain structure under the electricfield,we have made electrorheological fluid grating experimentally. We set up a liquid grating device withconcentrated giant electrorheological fluid illuminated by an uniform laser beam with small spot. Under theaction of electric field, we observed the standard optical grating diffraction phenomenon. Furthermore, wemeasured the experimental data such as grating constant and diffraction fringe spacing, and we summarized theexperimental data.To verify the physics in fluid grating,we compared traditional grating with liquid grating bymeasuring the grating constant for the same diffraction fringes , the error analysis shows that the fluid gratingdata fit very well.
