Damien P. KellyIn this paper, we address the problem of calculating Fresnel diffraction integrals using a finite number of uniformly spaced samples. General and simple sampling rules of thumb are derived that allow the user to calculate the distribution for any propagation distance. It is shown how these rules ... [J. Opt. Soc. Am.

Yansheng Li, Yihua Tan, Hang Li, Tao Li, Jinwen TianIn this paper, a biologically inspired multilevel approach for simultaneously detecting multiple independently moving targets from airborne forward-looking infrared (FLIR) sequences is proposed. Due to the moving platform, low contrast infrared images, and nonrepeatability of the target signature, ... [J. Opt. Soc. Am. A 31, 734-744 (2014)]

Omar Vázquez-Estrada, Augusto García-ValenzuelaRecently a multiple-scattering model for the reflectivity of a disordered monolayer of scattering particles on a flat surface was put forth [J. Opt. Soc. Am.29, 1161 (2012)]. The approximate theoretical model provides relatively simple formulas for the reflectivity, but it was developed for a ... [J. Opt. Soc. Am. A 31, 745-754 (2014)]

Philip C. L. StephensonA recurrence relation for the first-order Cartesian derivatives of the Zernike polynomials is derived. This relation is used with the Clenshaw method to determine an efficient method for calculating the derivatives of any linear series of Zernike polynomials. [J. Opt. Soc. Am. A 31, 708-715 (2014)]

Deyang Duan, Lu Zhang, Yunjie XiaIn this paper, we present a new scheme of thermal ghost imaging: visible ghost imaging with nonvisible light, which can overcome the disadvantages of conventional thermal imaging.

Elise W. Dees, Rigmor C. BaraasCarriers of red–green color-vision deficiencies are generally thought to behave like normal trichromats, although it is known that they may make errors on Ishihara plates.

J. M. Bosten, A. E. BoehmRed, green, blue, yellow, and white have been distinguished from other hues as unique. We present results from two experiments that undermine existing behavioral evidence to separate the unique hues from other colors.

Luping Du, Dingyuan TangSurface plasmons in graphene have many promising properties, such as high confinement, low losses, and gate-tunability. However, it is also the high confinement that makes them difficult to excite due to their large momentum mismatch with free-space mid-infrared light. We propose to use shaped ... [J. Opt. Soc. Am.

J. M. Bosten, A. J. Lawrance-OwenIf unique hues have special status in phenomenological experience as perceptually pure, it seems reasonable to assume that they are represented more precisely by the visual system than are other colors.

Christoph Witzel, Anna FranklinIf the most typical red, yellow, green, and blue were particularly colorful (i.e., saturated), they would “jump out to the eye.” This would explain why even fundamentally different languages have distinct color terms for these focal colors, and why unique hues play a prominent role in ...

Xun He, Christoph Witzel, Lewis Forder, Alexandra Clifford, Anna FranklinPrior claims that color categories affect color perception are confounded by inequalities in the color space used to equate same- and different-category colors.
