Gravitational Lensing by Spherical Lenses
International Journal of Astronomy and Astrophysics, 2014 In this work we introduced a new proposal to study the gravitational lensing theory by spherical lenses, starting from its surface mass density $Σ(x)$ written in terms of a decreasing function $f$ of a dimensionless coordinate $x$ on the lens plane. The main result is the use of the function $f(x)$ to find directly the lens properties, at the same time

Integration and Application of Microlens Arrays Within Heads-Up Displays
IEEE Photonics Journal, 2018 The proposed work targets a fundamental challenge in heads-up display technology—in that such displays must bring about tight imaging with a flat form factor to support integration within eyewear. A Gabor superlens, being coupled plano-concave and

Fast automated analysis of strong gravitational lenses with convolutional neural networks [PDF]
Nature, 2017 Quantifying image distortions caused by strong gravitational lensing—the formation of multiple images of distant sources due to the deflection of their light by the gravity of intervening structures—and estimating the corresponding matter distribution of

Practical Verification of Lenses: Implementing Formally Verified Lenses using agda2hs [PDF]
, 2022 agda2hs is a tool which translates a subset of Agda to readable Haskell. Using agda2hs, programmers can implement libraries in this subset of Agda, formally verify them, and then convert them to Haskell.
