New ray-tracing method for radial gradient-index lenses
نویسندگان
چکیده
A new method to derive algebraic formulae for tracing skew rays in radial gradient-index media is described. We obtained power series for the ray position and direction, optical path length and coordinates of the intersection point of the curved ray with the spherical end surface of the GRIN lens. All these formulae include the effects of terms up to the eighth power of the radius in the refractive index distribution.

Seidel aberration coefficients for radial gradient -index lenses
Short and accurate analytic formulas for the Seidel coefficients of gradient-index lenses with arbitrary radial refractive-index distributions have been obtained. Starting from analytic ray-tracing formulas, we have developed a technique for decomposing the two components of the transverse aberration of an arbitrary skew ray in surface and inhomogeneous transfer contributions and a technique fo...
متن کاملThree-dimensional ray tracing in spherical and elliptical generalized Luneburg lenses for application in the human eye lens.
Ray tracing in spherical Luneburg lenses has always been represented in 2D. All propagation planes in a 3D spherical Luneburg lens generate the same ray tracing, due to its radial symmetry. A geometry without radial symmetry generates a different ray tracing. For this reason, a new ray tracing method in 3D through spherical and elliptical Luneburg lenses using 2D methods is proposed. The physic...
متن کاملDr TIM: Ray-tracer TIM, with additional specialist scientific capabilities
We describe several extensions to TIM, a raytracing program for ray-optics research. These include relativistic raytracing; simulation of the external appearance of Eaton lenses, Luneburg lenses and generalised focusing gradient-index lens (GGRIN) lenses, which are types of perfect imaging devices; raytracing through interfaces between spaces with different optical metrics; and refraction with ...
متن کاملChromatic paraxial aberration coefficients for radial gradient-index lenses
A simple derivation of analytic expressions for the chromatic paraxial aberration coefficients of radial gradientindex lenses is presented. By decomposing the transverse chromatic aberration vector of an arbitrary paraxial ray in contributions from refraction at the surfaces and from transfer through the inhomogeneous media of the system, remarkably short formulas for the contributions of trans...
متن کاملChanges in spherical aberration after lens refilling with a silicone oil.
PURPOSE It may be possible to restore accommodation to presbyopic human eyes by refilling the lens capsular bag with a soft polymer. In the present study, optical changes were measured that occurred in a pig eye model after the refilling of the capsular bag. METHODS The optical power and spherical aberration in 10 isolated pig lenses were measured under different conditions. They were first d...
