摘要：
The invention relates to a device (100) and a corresponding method for thermoacoustic sensing, in particular thermoacoustic imaging, the device (100) comprising: a) an irradiation unit (10) configured to generate electromagnetic and/or particle energy exhibiting a first modulation, the first modulation comprising at least one frequency and to continuously emit the energy towards a target (1), whereby acoustic waves are continuously generated in the target, the acoustic waves exhibiting a second modulation, the second modulation comprising the at least one frequency and/or a harmonic frequency of the at least one frequency； b) a detection unit (20) configured to simultaneously detect the acoustic waves exhibiting the second modulation while the energy exhibiting the first modulation is being continuously emitted towards the target (1)； and c) a processing unit (30) configured to determine at least one thermoacoustic value of an amplitude and/or a phase of the second modulation of the acoustic waves at the at least one frequency and/or at a harmonic frequency of the at least one frequency. The invention allows for fast and economic thermoacoustic sensing, in particular imaging of a region of interest of an object.
