Handbook of optical and laser scanning

Working in optics, I purchased this book to get a wider scope of scanning techniques and possible optical schemes. The book is thick, up to eight hundred pages, and expensive. So, I expected a variety of optical schemes for laser/optical scanning. But I was disappointed with a great amount of topics, filling this book, which do not relate to scanning. For example, the chapters about M2 model, optical disk technology, image quality for scanning, are interesting in general but have rather distant relation to scanning. The chapter about motors and controllers is interesting, presenting the state-of-art of this technology, but it is overfilled with large, up to a page size, pictures which do not contain any information. For example, several pictures of printed-circuit boards with a great number of indistinguishable electronic components could be easily removed without any harm to the book. Also I doubt that pictures of standard diamond turning center, thin film deposition chamber, and other conventional industry technology are of any interest for professionals. At the same time such topics as infrared imaging scanners, reconnaissance systems, MEMS scanning/switching devices are completely ignored, as well as the rotating wedges technology. Summarizing, the size of this book could be made much smaller and the price lower without any loss of information.
