Optics of the Moon offers a modern approach to lunar remote sensing. It presents methods for interpreting optics of surfaces with complicated structures, in particular, the lunar regolith. For example, this book illustrates how phase-ratio techniques can lead to the detection of surface structure anomalies and describes polarimetric studies of the lunar surface and their use. This book addresses many questions related to the surfaces of the Moon, such as why the Moon looks like a ball at a large phase angle and like a disk in full moon, why the lunar surface has slight color variations, and why at large phase angles its polarization degree closely correlates with albedo. Including historical perspectives, case studies, maps, and figures to enhance the understanding of both theory and techniques, Optics of the Moon is a valuable resource for researchers and students in lunar and planetary science and remote sensing.
