OPTICAL TOMOGRAPHY BY THE TEMPORALLY EXTRAPOLATED ABSORBENCY METHOD

The concept of the temporally extrapolated absorbance method (TEAM) fo r optical tomography of turbid media has been verified by fundamental experiments and image reconstruction. The TEAM uses the time-resolved spectroscopic data of the reference and object to provide projection d ata that are processed by conventional backprojection. Optical tomogra phy images of a phantom consisting of axisymmetric double cylinders we re experimentally obtained with the TEAM and time-gating and continuou s-wave (CW) methods. The reconstructed TEAM images are compared with t hose obtained with the time-gating and CW methods and are found to hav e better spatial resolution. (C) 1996 Optical Society of America .
