    "abstract": "A method for determining the positions of hologram dislocations relative to\nthe optical axes of entangled Laguerre Gaussian modes is proposed. In our\nmethod, the coincidence count rate distribution was obtained by scanning the\nposition of one of the holograms in two dimensions. Then, the relative position\nof the hologram dislocation was determined quantitatively from the positions of\nthe minimum and maximum coincidence count rates. The validity of the method was\nexperimentally verified, and in addition, an experiment demonstrating the\nviolation of the Clauser-Horne-Shimony-Holt inequality was performed using the\nwell-identified optical axes of the entangled modes.",
