Abstract
In this paper, we demonstrated optical imaging of objects hidden behind highly turbid media with a femtosecond heterodyned optical Kerr gate (HOKG). The experimental results showed that when compared with traditional optical Kerr gated (OKG) imaging, the HOKG imaging system provided higher image sharpness and higher spatial resolution. In traditional OKG imaging system, low pass filtering due to a photoinduced soft aperture decreased the image sharpness. When the HOKG was used, the high spatial frequency components of the object could be effectively compensated.
