In this paper we are interested in reconstructing, by optical methods, a three-dimensional spatial distribution of a local parameter such as an attenuation coefficient or small differences in the refractive index of objects which are relatively transparent to electromagnetic energy.
We present a computer-controlled optical tracing system to produce the different-amplitude filters needed for the optical treatment and an interferometric device for scanning phase objects.
A new technique for coding image data allows the reconstruction of 3D-amplitude and phase objects to be performed without long and expensive numerical treatments.
