This is a practical guide to one of the hottest fields in electronics and optical circuits. A collection of hands-on experiments and projects for the student, technician, and hobbyist, it explains optoelectronics in nontechnical terms. Projects show how optical circuits work and how to use them in practical and efficient ways. You'll save time, money, and energy with dozens of do-it-yourself projects, from laser alarm systems to high-speed fiberoptic data links. Circuit diagrams, schematics, and complete parts lists accompany each project, and an appendix lists suppliers for needed parts.
