Abstract :
Methods that include diffraction effects are discussed for the tomographic reconstruction of the complex index of refraction within a soft-scattering object. The methods are Fourier-domain based and are threfore computationally efficient. An important signal-processing issue is shown to be the determination of the unwrapped phase of the sensed fields. The theoretical presentation is followed by examples of experimental results.
