    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.
