Deflection of light with the equivalence principle
1997A thorough treatment of the Strong Equivalence Principle is presented, demonstrating its failure in dealing with non-uniform gravitational fields. In particular, a calculation utilising the equivalence principle is shown to produce an incorrect rate of deflection of light. This calculation is used as a tool to investigate the nature of this deflection,

Electrooptic light-beam deflection
IEEE Spectrum, 1968The impetus given display, recording, computer, and space technologies by the revolutionary discovery of the laser has created an ever-increasing need for controlled optical-beam deflection techniques. Those that have been developed thus far, usually employing mechanical or acoustical methods, have had either high insertion loss or limitation on ...

Light Deflection in Curved Spacetime
2018Before turning to lensing by arbitrary mass distributions, we would do well to remember that the Newtonian deflection angle is off from the actual value by a factor of two. Narrowly speaking, the result of this chapter will be that factor. More broadly, though, understanding how gravitational lensing is an inevitable consequence of general relativity ...

Optically induced light deflection
Journal of Optics, 1984Refractive index changes are induced in real time in photosensitive materials through light beam interference (control beam). Deflection of a laser beam interacting with this phase grating is achieved when the grating parameters are modified. This is obtained by shifting the wavelength of the control beam.

DEVICE FOR DEFLECTING A LIGHT BEAM
1990The source of light of a large-area laser display panel is a laser (16). A deflecting unit (14) is connected downstream of said laser and is controlled by a process control computer (42) using signals of the type normally used to produce vector graphics on monitors.
