Abstract
For extracting the absorber information in a scattering medium, we investigate the temporal-spatial characteristics of optical intensity distribution ratio by solving the time-dependent photon diffused equation. Numerical results indicated the output power ratio distribution with short accumulated time is effective to obtain the reconstructed absorber with the narrow width. There is no influence of the temporal and spatial widths of the input pulsed light on the reconstructed property. In the numerical conditions used in the paper, the short accumulated time provides 60% of reconstructed absorber size obtained at the saturated time.
