A femtosecond time gating of cross correlation second harmonic generation is shown to be a versatile technique to image objects through various highly scattering medium, and optical coherent tomography (OCT) is achieved preliminarily. The ballistic and snake pulse component, that contain the information of the objects are effectively selected, while the diffuse component which contributes bright background noise to the image is eliminated by time gating of femtosecond cross correlation second harmonic generation. The SHG one dimensioanl and two dimensional pictures of objects hidden in highly scattering medium are recorded, respectively.
