Abstract
We have analyzed the beam-wave propagation in random media, and applied it to the transillumination imaging using practically useful light-beam illumination. In light-beam illumination, it is difficult to distinguish the absorber in a transillumination image. The effectiveness of proposed scattering suppression was examined when the absorber existed in off-axis area. Fig. 1 shows the result with the absorber in 10 mm depth from the an observation plane and 20 mm from the light axis. Using the proposed technique, we can recognize the absorber in the transillumination image even if we cannot recognize it in the observed image. The effectiveness of the proposed technique was verified.
