Abstract

We report two-dimensional imaging through a liquid scattering medium by noncollinear femtosecond parametric amplification in a reflection configuration. The experiment presented permits direct observation at video rate of two-dimensional images with $24‐\mathit{\mu }\mathrm{m}$ depth resolution and $90‐\mathit{\mu }\mathrm{m}$ 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.
