ABSTRACT:
Acoustic near field measurement apparatus uniquely featuring mechanical eomy, in terms of placement and motion of one or more acoustic measurement devices, which is accorded by the geometric character of a structure having indicia of symmetry. One or more devices are arranged, and/or caused to move with up to three degrees of freedom, so as to manifest conformance with respect to the surface of the structure. If desired, virtually complete acoustic near field mapping of the structure can be effectuated. Examples of the various embodiments of this invention include: circumferentially conformal arrayal of devices in combination with longitudinal movement of the arrayal; longitudinally conformal arrayal of devices in combination with circumferential movement of the arrayal; movement of one or more devices in a path or paths which are circumferentially conformal; movement of one or more devices in a path or paths which are longitudinally conformal; movement of one or more devices in a path or paths which are radial. For some embodiments a single device can be caused to move circumferentially, longitudinally and radially, and thus is provided three degrees of freedom. The apparatus according to this invention is more feasible and reliable than previous apparatus, especially for larger structures.
