A proposed design of the multidirectional holographic interferometer (MHI) with diffusive illumination in 3D dodecagon geometry for optical tomography is presented. The beam from Nd-YAG laser is divided and transformed to six object beams that incident to diffusors and illuminate the cross section area. The optical axes of reference beams lie in six vertical planes that are turned 30 degrees to each other, which is the specific of our design. Next is discussed the constructional design of mechanical realization of filtering and collimating optics as well as the ways of traction of the rotationally embedded scanning system of CCD cameras. Finally, optical and mechanical properties of interferometer are digestedly summarized.
