Studies on Acoustic Lens Imaging of Photoacoustic Signal
A new photoacoustic tomographic imaging mode by using acoustic lens directly imaging is put forward, acoustic lens response is figured out and distribution of criterion sample at image plane in a known sound field is measured. Considering sound resource point of cylinder piston, a theoretical correction to sample imaging is carried out and the results are analysed. Investigation indicates that it is feasible for photoacoustic tomographic imaging by acoustic lens. By picture reconstruction, the images of eyewinker in tissue are obtained. The axial resolution and transverse resolution are very high.
