Abstract
Abstract The orientation-dependence of the interference/diffraction patterns of the 1D-double slit, 2D-cross-double slit, 1D-grating and 2D-cross-grating experiments have been studied experimentally and theoretically. The universal phenomena of the curved, expanded, inclined and mirror-symmetric pattens were reported. However, the above experiments were limited to certain orientations, namely rotating the diaphragm/grating around either one axis or two axes. We show that, for certain orientations by rotating the grating around 3 axes, the spacings between adjacent diffraction orders are non-uniform. From the “starting order” to the “ending order”, the spacings between adjacent diffraction orders gradually increase. This extraordinary phenomenon challenges the existing theories.The above observed phenomena provide the comprehensive information to theoretical study of the double slit/grating experiments. We suggest that the complete mathematical model should contain three rotation angles as parameters and should be able to describe the phenomena of the non-uniform-spacing, curved, expanded, inclined and mirror-symmetric patterns consistently.
