Paper Abstract

A few schemes will be described in which ultra short pulses are used to see through highly scattering specimens, as typified by biological objects. The information thus obtainable should be similar to X-ray pictures and reveal details about structure in the inside of the object by fleeting shadows on the exit skin. The schemes to be analysed are: The fast Kerr gate followed by photographic film, a holographic approach using high resolution film (the few experiments reported in this paper refer exclusively to this scheme) and various schemes involving non linear effects including four wave mixing. A few remarks will be made about peculiarities resulting from the shape of the wavefronts involved in ultra short pulse imaging and a few very preliminary experimental observations will be reported.
