Simultaneous measurement of two orthogonally polarized beams upon diffraction from a substrate is done to determine properties of the substrate. Linearly polarized light sources with their radiation polarized in orthogonal directions are passed via two non-polarizing beamsplitters, one rotated by 90° with respect to the other. The combined beam is then diffracted off a substrate before being passed back through a non-polarizing beamsplitter and through a phase shifter and a Wollaston prism before being measured by a CCD camera. In this way, the phase and intensities for various phase steps of the two polarized beams may thereby be measured and the polarization state of the beams may be determined. If the phase shifter is turned to zero (i.e. with no phase shifting), the grating of the substrate has its parameters measured with TE and TM polarized light simultaneously with the same detector system.
