An experimental system for time resolved optical tomography is constructed by Ti∶Sapphire laser and syncroscan streak camera. With 3 dimensional step motor driving stage, the system can scan the object to be imaged in a parallel beam mode analogous to X ray CT, by which the time resolved projections at different incident angles can be obtained automatically. By applying the relevant image reconstruction algorithm, the promising images have been produced from the measurements for three kinds of tissue like phantoms that represent the different combinations of the absorption and scattering properties of the embedded single inclusion. The results indicate this system as a reliable and ideal platform for optical tomography research.
