We present reconstructions of a three-dimensional object imaged in reflection mode through a turbid medium, using time-gated Raman amplification. We demonstrate a less than 1-cm depth resolution at a laser-power-limited viewing distance of 8.5 attenuation lengths from an object with a rough metallic surface. We show that, even at a viewing distance of 10.5 attenuation lengths, the imaging system is power limited rather than backscatter limited.
