Abstract

We review the noise characteristics and the low-light-level imaging capabilities of a stimulated Raman amplifier and show how these properties can be combined with time-gating capabilities to image through dense scattering materials. Using 30 psec time-gating pulses, images were obtained of a resolution bar chart viewed through either a suspension of 0.364 micrometers polystyrene spheres where the forward attenuation due to scattering was e²⁸, or though a non-dairy creamer solution where the attenuation was up to e³³. At the highest scattering attenuation levels these images could not be detected by any conventional imaging method.
