Physical-model-based reconstruction of axisymmetric three-dimensional sound field from optical interferometric measurement

Optical interferometric measurement methods for sound fields have garnered considerable attention owing to their contactless nature. The capabilities of non-invasive measurement and reconstruction of three-dimensional sound fields are significant for characterizing acoustic transducers. However, thr...
