Truncated corner cubes with near-perfect retroreflection efficiency.

چکیده
By isolating a finite effective volume from a conventional triangular pyramid corner cube, we obtained truncated corner cube structures with greatly enhanced retroreflection efficiency. We explore an optimal truncated corner cube with near 100% retroreflection efficiency based on the expectation that the traveling paths of the optical rays can be localized in the finite effective volume of the structure, and, as a result, truncated corner cubes with perfect efficiency can be produced. As a case study, the retroreflection efficiency of a commercialized 3M truncated corner cube sample is evaluated. Furthermore, it is shown with numerical verification that a truncated corner cube array sheet with near-perfect retroreflection efficiency can be produced.

Geometrical optics analysis of the structural imperfection of retroreflection corner cubes with a nonlinear conjugate gradient method.
Geometrical optics analysis of the structural imperfection of retroreflection corner cubes is described. In the analysis, a geometrical optics model of six-beam reflection patterns generated by an imperfect retroreflection corner cube is developed, and its structural error extraction is formulated as a nonlinear optimization problem. The nonlinear conjugate gradient method is employed for solvi...
متن کاملThe (non-)existence of perfect codes in Lucas cubes
A Fibonacci string of length $n$ is a binary string $b = b_1b_2ldots b_n$ in which for every $1 leq i < n$, $b_icdot b_{i+1} = 0$. In other words, a Fibonacci string is a binary string without 11 as a substring. Similarly, a Lucas string is a Fibonacci string $b_1b_2ldots b_n$ that $b_1cdot b_n = 0$. For a natural number $ngeq1$, a Fibonacci cube of dimension $n$ is denoted by $Gamma_n$ and i...
متن کاملCrowd Simulation via Texture Synthesis
This paper presents a crowd simulation as a novel application of texture synthesis. The motion of autonomous agents is simulated using arbitrarily complex behavior, and captured to a 3D (i.e. animated) texture. The simulation is then expanded to a much larger number of agents using texture synthesis techniques. We make use of corner cubes for the synthesis, which are an extension to 3D of corne...
متن کاملPoisson Sphere Distributions
We present a method for efficiently generating Poisson sphere distributions, the three-dimensional equivalent of Poisson disk distributions. Our method is able to generate arbitrarily large Poisson sphere distributions in real time, and allows local evaluation of the generated distributions. The method we present is based on cubes with colored corners, called corner cubes, an extension of corne...
متن کاملEffect of retroreflection on a Fizeau phase-shifting interferometer.
Phase errors in a Fizeau phase-shifting interferometer caused by multiple-reflected beams from a retroreflective optics, such as a corner cube and a right-angle prism, are studied. Single- and double-pass configurations are presented, and their measurement results are compared. An attenuator is not needed in a double-pass configuration because light is reflected by the retroreflective optics tw...
