Geometry-invariant gradient refractive index lens: analytical ray tracing.
A new class of gradient refractive index (GRIN) lens is introduced and analyzed. The interior iso-indicial contours mimic the external shape of the lens, which leads to an invariant geometry of the GRIN structure. The lens model employs a conventional surface representation using a coincoid of revolution with a higher-order aspheric term. This model has a unique feature, namely, it allows analy...
متن کاملRay-tracing and Interferometry in Schwarzschild Geometry
Here, we investigate the possible optical anisotropy of vacuum due to gravitational field. In doing this, we provide sufficient evidence from direct coordinate integration of the null-geodesic equations obtained from the Lagrangian method, as well as ray-tracing equations obtained from the Plebanski’s equivalent medium theory. All calculations are done for the Schwarzschild geometry, which resu...
متن کاملRefractive Projection and Ray Tracing
Multi-cameras system is widely applied in 3D computer vision especially when multiple 11 cameras are distributed on both sides of the measured object. The calibration methods of multi12 cameras system are critical to the accuracy of vision measurement and the key is to find an 13 appropriate calibration target. In this paper, a high-precision camera calibration method for multi14 cameras system...
متن کاملNew ray-tracing method for radial gradient-index lenses
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 refrac...
متن کاملLens Aberrations and Ray Tracing
When beam quality is a concern in an optical setup, lens aberrations are an undesired side-effect. Which aberration affects a particular experiment is not always as obvious as one would like. Take for example, the simple goal to concentrate the maximum amount of optical power at a certain point using a lens. The first “obvious” requirement is that the initial beam should be well collimated, sen...
