Reflectivity and Color of Meteorites

Reflectivity Color Correction in Gabor Deconvolution

Summary White reflectivity is not a fundamental assumption in the convolutional models. However the deconvolution algorithms should be modified slightly to honour color in the reflectivity series. This color correction is just possible when enough well-log information is available to build a mathematical model for the regional reflectivity. A method for correcting reflectivity color effects in ...

Petrology and geochemistry of whole rock of Shahdad meteorites

In this study, meteorite pieces, with total weight of 259 grams, have been studied which is not listed in the world bulletin of meteorites. In order to classify these samples, after preparing microscopic thin sections and performing accurate petrography, using geochemical data of the major elements and trace elements of whole rock, obtained from XRF and ICPMS methods in Zarazma company’s labora...

High levels of reflectivity and pointillist structural color in fish, cephalopods, and beetles.

Vignolini et al. (1) reported the discovery of a multilayer structural reflector in the fruit of the herbaceous perennial Pollia condensata. The structural mechanism is remarkable, with a combination of different cells reflecting left-handed or righthanded circularly polarized light. However, several other significant contributions to the field of structural color deserve to be highlighted alon...

Calculation Methods for Digital Model Creation Based on Integrated Shape, Color and Angular Reflectivity Measurement

The paper presents a complete methodology for processing sets of data registered by the means of a measurement system providing integrated 3D shape, multispectral color and angular reflectance characteristic. The data comprise of clouds of points representing the shape of the measured object, a set of intensity responses as a function of wavelength of incident light used for color calculation a...
