Frequency-domain optical diffuse tomography: trajectory approach to the problem of reconstruction

The paper is devoted to development of the reconstruction algorithm for optical diffuse tomography using frequency-domain technique. On the base of theoretical investigations and experimental results a new method is proposed for the description of propagation through strongly scattering objects of the optical radiation generated by intensity modulated CW laser source. The method designed for developing the fast trajectory algorithm of tomographic reconstruction of an object's internal structure with separation of absorbing and scattering parameters. The reconstruction experiment has shown that the net processing time was not over than 0,3 s for 2D image. The presented images illustrate the applicability of this algorithm for the optical diffuse tomography.
