In turbid media such as biological tissues and living organisms, light is scattered randomly so that it is
very diffi cult to obtain useful information inside the area of interest. Even in such situation, wavefront
shaping can be used to focus and manipulate the spatial and temporal properties of light by controlling
the many degrees of freedom of the optical phase in the incident beam. In this review, we explain the
principle of the wavefront shaping and describe a couple of the previous studies to demonstrate the
viability of this method. We also discuss potential application to control the temporal properties of
ultrafast laser pulses both in spatial and temporal domain. This approach will open many new ways for
biological imaging and photonics by combining with nonlinear optical effects.
