Abstract
An alternative approach for data evaluation in thermoacoustic ultrasound measurements is investigated. In contrast to methods previously described, the transient temperature profile measured at the rear side of an insonified absorber is used instead of the temperature increase measured at equilibrium. The method considerably reduces the measurement time and expands the practical applicability of the thermoacoustic sensor concept.
