中文摘要 | We propose and demonstrate an experimental method for measuring the period difference in grating pair. The method uses the compensating relationship between line-density difference and the Littrow-angle difference of gratings. Far-field intensity patterns of 0th- and -1st-orders diffraction beams are monitored for alignment during the angle measurement. For a pair of similar to 0.676 mu m period gratings, the relative period difference was measured to be 798.4 x 10(-6) with a standard deviation of 2.0 x 10(-6). (C) 2008 Elsevier B.V.
