Abstract

We use blind deconvolution methods in optical diffusion tomography to reconstruct images of objects imbedded in or located behind turbid media from continuous-wave measurements of the scattered light transmitted through the media. In particular, we use a blind deconvolution imaging algorithm to determine both a deblurred image of the object and the depth of the object inside the turbid medium. Preliminary results indicate that blind deconvolution produces better reconstructions than can be obtained using backpropagation techniques. Moreover, it does so without requiring prior knowledge of the characteristics of the turbid medium or of what the blur-free target should look like: important advances over backpropagation.

Fig. 3. The different targets used to generate the experimental data. The first two targets, from left to right, were positioned behind a 2.5 cm thick phantom. The third target (far right) was imbedded in the center of a 5.5 cm thick phantom. From left to right: F-111 model aircraft, F-18 model aircraft, and Boeing 747 model aircraft. The F-111 and F-18 aircraft models, when illuminated and viewed through the turbid phantom, produce similar images (see Fig. 4). This provides a stringent test of the resolving capability of the two restoration algorithms considered in this work.
