Karazin popup.description2 The object of study is a gravitationaly lensed quasars (GLQ). The aim of the work was to develop a method of detecting hidden mass, which, according to modern concepts, can be a significant part of the mass of a galaxy presented by dark compact objects. In the course of this work we carried out more rigorous analysis of the quasar light passing through the layer of random mass uniformly distributed in the volume. The analysis shows that in this case there is a violation of complete correlation of changes in the brightness of the quasar components at different wavelengths, as well as with images taken by telescopes of significantly different diameters. In particular, the gravitational amplification should decrease with increasing of diameter of the telescope. Calculations show that this effect can be observed when changing the aperture on the 6-m telescope. This will enable a direct estimate of the number of compact masses located in the light path of the quasar and assess the size of the emitting area of the quasar at various wavelengths. Further development of these studies may lead to the emergence of a special tool, which will assess the contribution of invisible compact mass to the total mass of matter distributed in galaxies, and can make a significant contribution to solving the fundamental problem of the distribution of dark matter in the universe. At the present stage there was a decision on the temporary cessation of this work due to lack of funding, according to the article "Travel expenses" for observation.
