Abstract

For identification of a phantom (hidden foreign object) inside turbid medium with different optical properties the time of flight (TOF) technique was used. Nd:YAG-laser (X1064nm) as a light source and a streak camera with ultimate time resolution of l.5ps were employed. Analysis of laser light transmited through an experimental medium (a 2mm metal strip located inside a diluted milk) was perfomed with the help of this camera and read out system. Transmission profiles have shown that contrast ratio depends on the object position and medium concentration. Theoretical calculations made by Monte-Carlo simulation were in a good agreement with the experimental results.
