An important limiting class of rays that has many applications are the so-called paraxial rays, which lie throughout their length so close to the optical axis that their aberrations are negligible. The ray tracing formulas for paraxial rays contain no trigonometric functions and are therefore well...
X-ray spectromicroscopy with a full-field imaging technique is a powerful method for chemical analysis of heterogeneous complex materials with a nano-scale spatial resolution. For imaging optics, an X-ray reflective optical system has excellent capabilit

The synthesized silicates will supplement our knowledge of possible rare-earth minerals existing in hydrothermal systems, which is important for analyzing the distribution spectra of rare elements, which are widely used for diagnostics of geochemical processes and determination of sources of ore materials...
In this paper, we present our polynomial optics-based ray transmission model for simulating the lens flares of optical systems. Our proposed method facilitates the high-quality, real-time simulation of lens flare ghosts while properly treating all important characteristics of the phenomenon. Compared ...
In physics, ray tracing is a method for calculating the path of waves or particles through a system with regions of varying propagation velocity, absorption characteristics, and reflecting surfaces. Under these circumstances, wavefronts may bend, change direction, or reflect off surfaces, complicating...
Since we are dealing with single mode fibers, these higher order modes are not important. Gaussian Optics for Collimator Outlines Introduction Scalar Maxwell Equation and Gaussian Solution Gaussian Approximation of Single Mode Fibers Ray Tracing and ABCD Matrix ...
In high-resolution diffractometers, X-ray beams are conditioned by X-ray optics based on single or multiple crystals, and goniometers with accuracies of 10−4degrees both on the sample and the detector rotation axes are used. By this technique, it is by far more convenient to m...
Thus we reach the important conclusion that we can eliminate coma by a suitable choice of stop position if there is spherical aberration present; indeed, this result is implicit in the OSC formulas in Section 9.3. Furthermore, we can flatten the tangential field by a suitable choice of stop ...
