Linear Diffraction Grating Interferometer (LDGI) is a long stroke and nanometer resolution displacement sensor for any linear stages. The principle of this diffractive interferometer is based on the Littrow configuration and phase information encoded by the ±1st order beams diffracted by a holograph...
