When a short laser pulse illuminates the virtual absorber in a scattering medium, the absorber will generate pressure distribution which is linearly proportional to the optical absorption of the medium. The laser induced ultrasonic signals are imaged with an acoustic lens. A 64-element linear transducer array is one-dimensionally scanned on an imaging plane to acquire the acoustic pressure distribution by high speed acquisition card, and the signals are recorded and reconstructed by a computer. A new fast photoacoustic tomograph imaging system is demonstrated. It can acquire and record the data for a certain depth. The system can reconstructe different images from different planes at the same time only by selecting different numbers of columns in the datasheet. We experimentally obtain photoacoustic tomography images on different planes in the scattering media successfully. The images are vivid and contrast clearly with the background. This method directly provides images on different object planes of absorbing structures at the same time without the need of computational reconstruction.
