1. A method of optical reading comprising the steps of:

  • focusing, along an optical path, a two-dimensional image of an object being read;

    projecting the two dimensional image toward a collection system comprised of one or more two-dimensional sensor arrays, each sensor array being arranged at a tilt angle α

    with respect to the optical path according to the Scheimpflug principle;

    detecting the two dimensional image at differing rotational angles relative to the optical path while maintaining the tilt angle α

    of the sensor array with respect to the optical path.
