INVERSE SPECTRAL PROBLEMS USED FOR THE SYNTHESIS OF DIFFUSIONAL LIGHT GUIDES.

If diffusional waveguides are investigated then the successive formulation and analysis of two types of inverse problems are required: electrodynamic and heat- and mass-exchange problems. An investigation was conducted of the laws connecting the diffusional processes of synthesis of waveguides with their optical properties. It is shown that inverse spectral problems can be used in problems relating to both electrodynamics and heat and mass exchange. In this work the authors systematically analyzed two inverse problems which have application to the formation of optical devices with assigned transmission characteristics.
