Abstract :
An improved method and technique for magnetic field topology visualization with a mater to solve some important tasks in criminalistics and partial data loss restoration are reported. It is shown that the special types of film magneto-optic garnet transducers (MOGT) make possible to image and measure nonuniform field distribution on 10-6-10-2 m area with ~60 dB dynamic range. Variants of MOGT which are successfully used in the special image processing complex for signalogram analysis are described
