Visibility of natural tertiary rainbows.
Naturally occurring tertiary rainbows are extraordinarily rare and only a handful of reliable sightings and photographs have been published. Indeed, tertiaries are sometimes assumed to be inherently invisible because of sun glare and strong forward scattering by raindrops. To analyze the natural tertiary's visibility, we use Lorenz-Mie theory, the Debye series, and a modified geometrical optics...
متن کاملSpectral measurement and modeling of natural rainbows.
Although quantitative observations of rainbow spectra, colors, and luminances are needed for any comprehensive analysis of rainbow scattering theory, very little such data has been published. But new remote sensing tools now make possible the detailed spectral and colorimetric measurement of natural rainbows, which here are defined as bows seen in sunlit rain or water-drop sprays. To measure th...
متن کاملColors and Spectra of Kuiper Belt Objects1
We present new measurements of the optical colors of Kuiper belt objects, principally from the Keck 10 m telescope. The measurements conÐrm the existence of a wide spread in the B[V , V [R, and R[I color indices as we found previously. Relative to the sun, the Kuiper belt objects exhibit reÑected colors from nearly neutral to very red. The optical and optical-infrared (V [J) color indices are m...
متن کاملAnalyzing Hyperspectral Data with Independent Component Analysis
Hyperspectral image sensors provide images with a large number of contiguous spectral channels per pixel and enable information about diierent materials within a pixel to be obtained. The problem of spectrally unmixing materials may be viewed as a speciic case of the blind source separation problem where data consists of mixed signals (in this case minerals) and the goal is to determine the con...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
