Abstract
A numerical simulation of the inverse image formation of opaque objects by focusing the transmitted radiation into the absorbing medium is performed. It is shown that the process strongly depends on the ratio of the size of the object and the illuminating beam. Inverse image conversion exceeds 350% for small-scale objects, relative to the initial intensity of the beam.
