GRIN Lenses for Uniform Illumination,nd decreases continuously from the axis to the periphery along the transverse direction. The focusing and transforming capabilities of GRIN lenses come from a quadratic variation in refractive index with radial distance from the axis. In a GRIN lens, rays follow sinusoidal trajectories as if they we

The Talbot Effect in GRIN Media,eived wide attention. Fundamental properties and many practical applications of the Talbot effect in a homogeneous medium have been considered [7.1–7.10]. The Talbot effect has also been studied in the context of atom optics because of similarities between the Schr?dinger and the paraxial wave equat

GRIN Crystalline Lens,camera. The optical system of the eye forms an image on the retina, whereas the camera lens forms its image on film. The camera must be focused by changing the distance from the lens to the film. However, a change in the configuration of the crystalline lens (human lens) occurs when the eye needs to

Optical Connections by GRIN Lenses,f-axis imaging and Fourier transforming, which are of great importance in these fields. Taking advantage of the inherent features of the lenses, many optical configurations for connecting fibers, sources, or detectors by GRIN lenses have been analyzed for coupling and sensing purposes [9.1–9.4]. We
