适用范围： Note 1-As used in this practice, orthogonal orientation refers to alignment of the longitudinal axis of a test object along the XYZ axes of the Cartesian coordinate system; is horizontal and across the portal, is vertical, and is in the direction of travel through the portal. Note 2-Unsymmetrical metal objects possessing a primary longitudinal component, such as handguns and knives, usually have one particular orientation that produces the weakest detection signal. The orientation and the path through the detector aperture where the weakest response is produced may not be the same for all test objects, even those with very similar appearance. Note 3-In the case of multiple specified test objects or for test objects that are orientation sensitive, it may be necessary to map each object several times to determine the worst-case test object or orientation, or both.
