A system to perform photoacoustic imaging of a sample comprises: a laser source for emitting a pulsed beam, a solid immersion lens (2) having a substantially flat surface to contact the sample and a curved, convex surface to be impinged by the pulsed beam, said lens being designed to allow the focus of the said beam on the said substantially flat surface, at least one sensor (3) for producing an electric signal when receiving the acoustic wave (4a) generated by the sample on absorbing energy from said beam, the at least one sensor being fitted to the surface, means (8) for moving the beam in order to scan the sample, and means for receiving the signals produced by the at least one sensor and producing an image. |
