We report two-dimensional imaging through a liquid scattering medium by noncollinear femtosecond parametric amplif ication in a ref lection configuration. The experiment presented permits direct observation at video rate of two-dimensional images with 24-mm depth resolution and 90-mm transverse resolution for an area with a 2.5-mm diameter on the object. These resolutions are achievable through a turbid phantom with a depth near 12 scattering mean free paths in double pass
