Good optical design is not in itself adequate for optimum performance of optical systems. The mechanical design of the optics and associated support structures is every bit as important as the optics themselves. Optomechanical engineering plays an increasingly important role in the success of new laser systems, space telescopes and instruments, biomedical and optical communication equipment, imaging entertainment systems, and more. This is the first handbook on the subject of optomechanical engineering, a subject that has become very important in the area of optics during the last decade. Covering all major aspects of optomechanical engineering - from conceptual design to fabrication and integration of complex optical systems - this handbook is comprehensive. The practical information within is ideal for optical and optomechanical engineers and scientists involved in the design, development and integration of modern optical systems for commercial, space, and military applications. Charts, tables, figures, and photos augment this already impressive handbook. The text consists of ten chapters, each authored by a world-renowned expert. This unique collaboration makes the Handbook a comprehensive source of cutting edge information and research in the important field of optomechanical engineering. Some of the current research trends that are covered include:

VOLUME 2: "Movies and Methods," Volume II, captures the developments that have given history and genre studies imaginative new models and indicates how feminist, structuralist, and psychoanalytic approaches to film have achieved fresh, valuable insights. In his thoughtful introduction, Nichols provides a context for the paradoxes that confront film studies today. He shows how shared methods and approaches continue to stimulate much of the best writing about film, points to common problems most critics and theorists have tried to resolve, and describes the internal contraditions that have restricted the usefulness of post-structuralism. Mini-introductions place each essay in a larger context and suggest its linkages with other essays in the volume. A great variety of approaches and methods characterize film writing today, and the final part conveys their diversity--from statistical style analysis to phenomenology and from gay criticisms to neoformalism. This concluding part also shows how the rigorous use of a broad range of approaches has helped remove post-structuralist criticism from its position of dominance through most of the seventies and early eighties. -- Publisher description.

Everyone has heard the story -- the dwarves, the talking mirror, the evil witch. But this tale doesn't belong to Snow White anymore.... Bert and Will, the twin sons of the baron of Ambercrest, are best friends. They do everything together and can't help it if trouble just seems to...find them. But the baron is fed up and has decided that separation will keep them out of mischief. One twin, he proclaims, will stay in Ambercrest for the summer, while the other will be sent to The Crags -- a foreboding, rocky outpost on the edge of the kingdom. It is there, hidden in a forbidden black chamber, that one of the boys discovers a bejeweled and mysterious mirror. What is the precious object? And why does it make him feel so...powerful? Soon the twins' kinship is replaced by dark magic and deceit, and a kingdom hangs dangerously in the balance. What becomes of one who is ruled by the forces of evil? And can brotherly love conquer a consuming quest for power?

Influence the unconscious mind. To practice Voodoo is to enter the ancient world of Magik, where secret arts developed from rituals held by ancient pagans, Native American tribes, Haitians, and Wiccans. Understand Voodoo’s underlying ideas and learn to make use of its powers with illustrated instructions and exercises. Use charms to bring good luck to your relationships, finances, and health--or curses to keep away harmful forces and persons. Make and employ the full range of sacred objects: dolls, candles, incense, ritual clothing, swords, knives, needles and nails, goblets, keys, mirrors, musical instruments, amulets, and masks, for charm or curse symbols to place in your room, car, or clothing. Breathing exercises enable you to enter trances, contact the unconscious and even the dead.
