Paper Abstract

Signal properties of continuous wave (CW) and photon density wave (PDW) detection of absorbing objects in turbid media are presented. The two-component solution of the radiation transport equation is obtained for CW and PDW field of a directed source. The amplitude and phase images of a black spherical object in highly scattering medium obtained by a double-position sensing technique are constructed. Signal to noise ratio for the PDW amplitude and phase and for the CW signal is calculated.
