我们证明了激光光束可以通过光扩散介质通过光声引导干涉聚焦汇聚到光吸收目标上。光的收敛是通过用一个可变形的镜子来塑造入射光的波前来实现的，以最大化光声信号，这与光吸收器处的散射光强度成正比。
We demonstrate that laser beams can be converged toward a light-absorbing target through optically diffusive media by using photoacoustic-guided interferometric focusing. The convergence of light is achieved by shaping the wavefront of the incident light with a deformable mirror to maximize the photoacoustic signal, which is propor tional to the scattered light intensity at the light absorber.
