In this paper, we consider the recovery of photon diffusion coefficient in the case of piecewise constant coefficients in optical tomography from boundary measurements of light propagation within a tissue. We propose an effective reconstruction algorithm to detect the number, the location, the size and the shape of piecewise constant coefficients. This problem is nonlinear and severely ill-posed, thus we should consider a regularisation technique in our approach in order to improve the corresponding approximation. We give several examples to show the viability of our proposed method. [ABSTRACT FROM AUTHOR]
