Using the Solar Gravitational Lens for Exoplanet Imaging
Viktor has been collaborating with researchers from the Jet Propulsion Laboratory on the advanced concept of a deep space observatory that would use the bending of light by the Sun and the resulting Solar Gravitational Lens (SGL) to image distant objects. The light amplification and resolving power of the SGL far exceed anything possible with realistic conventional instruments. At the same time, there are many severe challenges, both practical (distance, communication, navigation) and theoretical (imperfect lens, light contamination, integration times). Viktor will discuss these challenges as well as the strength of the mathematical model, developed with Slava Turyshev from JPL, that allows us to efficiently model the point-spread function of the SGL and convolve it with that of an optical telescope, to study image formation and signal-to-noise ratios.


About Viktor:
Viktor Toth is an IT professional and “part time” physicist from Ottawa, Ontario, Canada. He played a key role in the resolution of the Pioneer anomaly, the anomalous acceleration of the Pioneer 10 and 11 spacecraft, back in 2012. He has since collaborated with physicists from the Jet Propulsion Laboratory, from The Perimeter Institute in Waterloo, Ontario, and other institutions. Since 2017, he has been involved with research on using the gravitational field of the Sun, in the form of the Solar Gravitational Lens, to image distant objects, among them potentially life-bearing exoplanets. Viktor’s papers and publications can be accessed through his Web site, at
