Abstract: Instrument of mathematical modeling of trajectory characteristics of light at propagation in gravitational field of group of astrophysical objects has been suggested. The influence of gravitational field has been taken into account by introducing an effective index of refraction of vacuum. It is shown that difficult spatial structure of light forms on picture plane of observer at a asymetrical gravitational field. Estimation of spatial weakening of energy flux has been performed by summing of relative energetic portions of light and with help of calculation of light divergance. Comparison of results of light and partial modeling of light flux in gravitational field with different configuration has been performed.
Keywords: refraction of light, astrophysical objects, geometrical optics, gravitational lensing.
