Proposed schematic of terahertz low-coherent tomograph makes it possible to realize tomography of investigated stratified media with resolution, equal to 4l0, where l0 is the mean wavelength of the probing radiation, with a depth of few centimeters. The resolution of this type tomography is placed in interval~ 100 … 1000 microns. This resolution is few times better that resolution of often used famous tomographs in medicine practice, including magneto–resonance tomograph. Proposed schematic is based on using holography of focused images, holography on opposing beams, Michelson’s interferometer and spherical mirrors. This tomograph, possessing the high penetrating ability and the high resolution, can successfully to compete, for example, with magneto-resonance tomograph in those fields, where this tomograph widely applied.
