Description

Since conventional single frequency acoustical holography provides only poor axial resolution, this concept was improved with the multifrequency holography to enhance the imaging quality. This leads to long data acquisition times because of the need to measure each frequency. A further step towards a fast imaging system with good spatial resolution is broadband holography. Here, one illuminates the object with broadband signals in a single measurement procedure.
