LIGHT DEFLECTION IN PERTURBED FRIEDMANN UNIVERSES
, 1994
"... In this letter a new formula for light deflection is derived using only physically observable concepts. The general result is specialized to cosmological perturbation theory and expressed in terms of gauge–invariant perturbation variables. The resulting scalar, vector and tensor equations are supple ..."

A New Theory of Light Deflection Due to Gravitation
"... A new theory of light deflection due to gravitation is proposed based on Einstein Cartan Evans (ECE) unified field theory. It is shown that the Schwarzschild parameter of 1916 can be expressed as: α = −T/R where T/R is the ratio of torsion to curvature, c is the vacuum speed of light and G is Newton ..."

UCLIPT9908 The observable light deflection angle
, 1999
"... To the memory of Jacques Demaret The physical deflection angle of a light ray propagating in a spacetime supplied with Light deflection by a gravitational source played a crucial role in the early establishment of General Relativity. Nowadays, gravitational optics is systematically used to search f ..."

The measurement of the light deflection from Jupiter: Theoretical interpretation
, 2003
"... Equations of light, propagating from quasar to observer on earth, are integrated in the timedependent gravitational field of the solar system by making use of either retarded or advanced solutions of the Einstein field equations. This technique allows to separate explicitly the effects associated w ..."

Compressive Imaging and Characterization of Sparse Light Deflection Maps
, 2014
"... Light rays incident on a transparent object of uniform refractive index undergo deflections, which uniquely characterize the surface geometry of the object. Associated with each point on the surface is a deflection map which describes the pattern of deflections in various directions and it tends to ..."

Linearized gravity, Newtonian limit and light deflection in RS1 model
, 2002
"... We solve exactly the equations of motion for linearized gravity in the RandallSundrum model with matter on the branes and calculate the Newtonian limit in it. The result contains contributions of the radion and of the massive modes, which change considerably Newton’s law at small distances. The eff ..."

. The effects of ”shadow ” matter, which lives on the other brane, are considered and compared with those of ordinary matter for both positive and negative tension branes. We also calculate light deflection and Newton’s law in the zero mode approximation and explicitly distinguish the contribution of the radion
I ~ CALCULATION OF LIGHT DEFLECTION DUE TO GRAVITATION WITH THE ECE FORCE LAW.
"... by M. W. Evans and H. Eckardt, Civil List, AlAS and UPITEC. The vector formulation of Cartan geometry developed recently in this series of papers is used to develop the concept of orbital force and spin force from the first Maurer Cartan structure equation and applied to the light deflection due to ..."
