Theory of Reflectance and Emittance Spectroscopy
TL;DR: In this article, the authors present a review of vector calculus and functions of a complex variable and Fraunhoffer diffraction by a circular hole, and a miscellany of bidirectional reflectances and related quantities.
Journal ArticleDOI
Bidirectional reflectance spectroscopy: 1. Theory
TL;DR: In this article, an approximate analytic solution for the radiative transfer equation describing particulate surface light scattering, taking into account multiple scattering and mutual shadowing, was derived for the interpretation of reflectance spectroscopy of laboratory surfaces and the photometry of solar system objects.
Journal ArticleDOI
Bidirectional reflectance spectroscopy 3. Correction for macroscopic roughness
TL;DR: In this article, a mathematically rigorous formalism is derived by which an arbitrary photometric function for the bidirectional reflectance of a smooth surface may be corrected to include effects of general macroscopic roughness.
Journal ArticleDOI
Space weathering from Mercury to the asteroid belt
TL;DR: In this paper, a mathematical theory that describes the optical and magnetic effects of the sub-microscopic iron quantitatively is derived and applied to the regoliths of the Moon, Mercury and an S asteroid.
Journal ArticleDOI
Bidirectional reflectance spectroscopy. IV - The extinction coefficient and the opposition effect
TL;DR: In this paper, an analytical model was developed for the opposition effect (heiligenshein) in the case of light scattering from a semi-infinite, particulate medium with particles that are large relative to the wavelength.
