Micromachined Mirrors provides an overview of the performance enhancements that will be realized by miniaturizing scanning mirrors like those used for laser printers and barcode scanners, and the newly enabled applications, including raster-scanning projection video displays and compact, high-speed fiber-optic components.
Micromachined scanning mirrors are interesting for a wide variety of applications because of their potential low cost, high speed, low power consumption, and reliability. These mirrors can offer significant advantages over macro-scale mirrors, but the fundamental limitations of scanning mirrors have not been widely discussed.
Dr W J Jenkins In 1977 when the Sheffield Transfusion Centre took delivery of the first GROUPAMATIC blood grouping machine in the UK it was equipped with a sample identification system involving complicated and expensive disposable punched cards. In fact, the cards were so expensive that Dr Wagstaff was unable to find the revenue to support the system. A year later, when Brentwood took delivery of a GROUPAMATIC, we were faced with the same problem, but by chance we heard that KONTRON was developing a laser scanning system for bar code labels and we were able to have our machine modified. Subsequently the Sheffield machine was altered to take the bar code scanner. At about the same time the Bristol Centre was helping TECHNICON with the development of the AUTO GROUPER C-16, and fortunately they decided on a laser reader of the same type for bar code identification. Thus there were three centres with the capability for reading bar codes on blood grouping machines and it became necessary to find someone to produce the bar code labels. There was only on~ printer in the UK who could produce labels to the required specification. To cut the costs of printing, and in the hope of avoiding a wide variation in codes, I invited representatives of centres interested in the problem to a meeting, where we set up what we called the Group of Six. This later became an official Working Party of the Regional Transfusion Directors.
Bringing together scattered literature from a range of sources, Laser Spectroscopy and Its Applications clearly elucidates the tools and concepts of this dynamic area, and provides extensive bibliographies for further study. Distinguished experts in their respective fields discuss resonance photoionization, laser absorption, laser-induced breakdown, photodissociation, Raman scattering, remote sensing, and laser-induced fluorescence. The book also incorporates an overview of the semiclassical theory of atomic and molecular spectra. Combining background at an intermediate level with an in-depth discussion of specific techniques, Laser Spectroscopy and Its Applications is essential reading for laser and optical scientists and engineers; analytical chemists; health physicists; researchers in optical, chemical, pharmaceutical, and metallurgical industries. It will also prove useful for upper-level undergraduate and graduate students of laser spectroscopy and its applications, and in-house seminars and short courses offered by firms and professional societies.

Machine Trades Print Reading, a combination text and write-in workbook designed to help you develop the skills required to visualize and interpret industrial prints. The text begins with an overview of the role of prints in the design and manufacturing process and then teaches the fundamentals of visualizing shapes, line usage, title blocks and notes, math measurement, dimensions, and toldeances. Machine Trades Print Reading further explains details common to industrial prints and provides an intrroduction to geometric dimensioning and tolerancing. The final unit contains comprehensive review activities. Throughout the text, real industrial prints have been included to provide valuable hands-on learning opportunities.
