Paper Abstract

Optical Kerr gate with a function of light amplification and a femtosecond opening time in a special fast setup is applied to time-resolved imaging. Transient induced anisotropy created by a first pump pulse is canceled by the perpendicular-induced anisotropy which is created by a delayed pump. The transverse resolution of the image is better than 90 micrometers without degradation originated from optical Kerr effect or optical amplification process. Moreover, rather wide spectral band of the gate offers the possibility of spectroscopic imaging. 3D imaging of small- signal objects using the femtosecond amplifying optic al Kerr gate are demonstrated for several types of transmittance objects hidden behind light diffusers.
