"The Hatfield Lunar Atlas" has become an amateur lunar observer's bible since it was first published in 1968. <br> <br>A major update of the atlas was made in 1998, using the same wonderful photographs that Commander Henry Hatfield made with his purpose-built 12-inch (300 mm) telescope, but bringing the lunar nomenclature up to date and changing the units from Imperial to S.I. metric <br> <br>This edition is important since the fact is that modern telescope optics, digital imaging equipment and computer enhancement can easily surpass what was achieved with Henry Hatfield's 12-inch telescope and a film camera. This limits the usefulness of the original atlas to visual observing or imaging rather small amateur telescopes. <br> <br>The new, digitally re-mastered edition vastly improves the clarity and definition of the original photographs - significantly beyond the resolution limits of the photographic grains present in earlier atlas versions - while preserving the layout and style of the original publications. This has been achieved by merging computer-visualized Earth-based views of the lunar surface, derived from NASA's Lunar Reconnaissance Orbiter data, with scanned copies of Commander Hatfield's photographic plates, using the author's own software. <br> <br>The results is a "The Hatfield Lunar Atlas" for 21st century amateur telescopes up to and beyond 12-inch aperture.

This book presents the underlying physical picture and an overview of the state of the art of femtosecond supercontinuum generation in various transparent solid-state media, ranging from wide-bandgap dielectrics to semiconductor materials, and across various parts of the optical spectrum, from the ultraviolet to the mid-infrared. A particular emphasis is placed on the most recent experimental developments: multioctave supercontinuum generation with pumping in the mid-infrared spectral range, spectral control, power and energy scaling of broadband radiation and the development of simple, flexible and robust pulse compression techniques, which deliver few optical cycle pulses and which could be readily implemented in a variety of modern ultrafast laser systems. The expected audience includes graduate students, professionals and scientists working in the field of laser-matter interactions and ultrafast nonlinear optics.

<p><i>Biomedical Optics in Otorhinolaryngology: Head and Neck Surgery</i> gives an overview of current technology in biomedical optics relevant to the field of Otorhinolaryngology and head and neck surgery. It provides a comprehensive source of knowledge for researchers and active clinicians seeking information on the principles and practical use of novel diagnostic and therapeutic technology. </p> <p>While most books focus exclusively on laser surgery, which has been largely unchanged for the past 15 years, optical diagnostics and head and neck PDT (photodynamic therapy) are usually entirely overlooked. This book contains a basic introduction into the physics of light and its propagation, lasers and low-coherent light sources, and photon-tissue interaction in relation to therapeutic and diagnostic use. The principles of various imaging techniques are also discussed ( i.e. optical coherence tomography in its variations), as well as the principles and practice of lasers for surgical use on the therapeutic side. </p>

This fourth volume of Light Scattering Reviews is composed of three parts. The ?rstpartisconcernedwiththeoreticalandexperimentalstudiesofsinglelightsc- tering by small nonspherical particles. Light scattering by small particles such as, for instance, droplets in the terrestrial clouds is a well understood area of physical optics. On the other hand, exact theoretical calculations of light scattering p- terns for most of nonspherical and irregularly shaped particles can be performed only for the restricted values of the size parameter, which is proportional to the ratio of the characteristic size of the particle to the wavelength?. For the large nonspherical particles, approximations are used (e. g. , ray optics). The exact th- retical techniques such as the T-matrix method cannot be used for extremely large particles, such as those in ice clouds, because then the size parameter in the v- iblex=2?a/???,wherea is the characteristic size (radius for spheres), and the associated numerical codes become unstable and produce wrong answers. Yet another problem is due to the fact that particles in many turbid media (e. g. , dust clouds) cannot be characterized by a single shape. Often, refractive indices also vary. Because of problems with theoretical calculations, experimental (i. e. , la- ratory) investigations are important for the characterization and understanding of the optical properties of such types of particles. The ?rst paper in this volume, written by B. Gustafson, is aimed at the descr- tionofscaledanalogueexperimentsinelectromagneticscattering.

The Invisible Man is a science fiction novella by H. G. Wells. Originally serialized in Pearson's Weekly in 1897, it was published as a novel the same year. The Invisible Man of the title is Griffin, a scientist who has devoted himself to research into optics and invents a way to change a body's refractive index to that of air so that it neither absorbs nor reflects light and thus becomes invisible. He successfully carries out this procedure on himself, but fails in his attempt to reverse it. While its predecessors, The Time Machine and The Island of Doctor Moreau, were written using first-person narrators, Wells adopts a third-person objective point of view in The Invisible Man. A mysterious man, Griffin, arrives at the local inn of the English village of Iping, West Sussex, during a snowstorm. The stranger wears a long-sleeved, thick coat and gloves; his face is hidden entirely by bandages except for a fake pink nose; and he wears a wide-brimmed hat. He is excessively reclusive, irascible, and unfriendly. He demands to be left alone and spends most of his time in his rooms working with a set of chemicals and laboratory apparatus, only venturing out at night. While Griffin is staying at the inn, hundreds of strange glass bottles (that he calls his luggage) arrive. Many local townspeople believe this to be very strange. He becomes the talk of the village with many theorizing as to his origins. Meanwhile, a mysterious burglary occurs in the village. Griffin is running out of money and is trying to find a way to pay for his board and lodging. When his landlady demands that he pay his bill and quit the premises, he reveals part of his invisibility to her in a fit of pique. An attempt to apprehend the stranger is frustrated when he undresses to take advantage of his invisibility, fights off his would-be captors, and flees to the downs. There Griffin coerces a tramp, Thomas Marvel, into becoming his assistant.
