| Zusammenfassung | We have measured time-resolved transmittance of ps laser pulses through scattering suspensions of thickness d employing time-correlated single photon counting. When absorption is neglected time-resolved transmittance and its Fourier transform can be expressed in terms of scaled variables, i.e. time (Theta) and angular frequency (Omega) , respectively. We have complemented our investigations on resolution by imaging translucent and absorbing objects embedded in animal tissue in vitro. Objects below the resolution limit, i.e. bars with cross sections 6 mm by 3 mm were detected at the center position of tissue being 4 cm thick. This was achieved by selecting sufficiently short initial time intervals, corresponding to fractions f ( 0.1, enhancing contrast considerably in this way. |
