A new model of gravitational lens – high-resolution gravitational lens based on the metric of gravitational field produced by N moving and rotating finite-sized bodies – is proposed. The model is applied to the case of a double galaxy gravitational lens. It is pointed out that previous searches for gravitational lensing in double systems focused on eclipsing binaries and were based on the analysis of their photometric variability. Unlike other authors, we determined the extra terms to be added to the refraction angle to account for the motion and rotation of the bodies. We show that the allowance for the motion of galaxies decreases the shifts of the images of the lensed object and that this effect is detectable in the current state of astronomical observations.

Keywords: gravitational lensing: micro; galaxies: individual (NGC 4567, NGC 4568)
