We propose a method to suppress the speckle of optical Kerr gated (OKG) imaging in highly turbid medium using an 800-nm femtosecond laser, in which, the 800-nm fundamental frequency light and the supercontinuum (SC) containing the fundamental frequency are used as the gating beam and imaging beam, respectively. A sequence of images of a test chart hidden behind a highly turbid medium is obtained using the OKG technique. Compared with images obtained with OKG imaging using only the fundamental frequency, the image resolution and contrast of images obtained through OKG imaging using the SC-assisted fundamental frequency are both significantly enhanced.

Microscopic imaging of hidden objects in scattering media is demonstrated using a differential optical Kerr gate (DOKG). The results show that the high spatial frequency components of the imaged object filtered by the optical Kerr gate can be considerably compensated using the DOKG. Microscopic images with a maximal lateral resolution of $\sim 2$ - \mu \text{m} can be achieved. Compared with OKG microscopic imaging, the contrast of DOKG microscopic images is enhanced significantly. [ABSTRACT FROM PUBLISHER]

We have demonstrated the high time-resolved three-dimensional (3-D) imaging using a chirped supercontinuum (SC) and an ultrafast optical Kerr gate (OKG) generated with a femtosecond laser, in which a sapphire plate and a \Bi2\O3\–\B2\O3\–\SiO2 oxide glass (BI glass) were used to generate the chirped SC and the optical Kerr gate, respectively. The experimental results show that the 3-D imaging using BI glass offers better temporal and longitudinal spatial resolution compared with \CS2. [ABSTRACT FROM PUBLISHER]
