BERNARD BABANI BP194: Modern Opto Device Projects
-- In recent years, the range of opto devices available to the home constructor has expanded and changed radically. These devices now represent one of the more interesting areas of modern electronics for the hobbyist to experiment in, and many of these devices have useful practical applications as well.
-- This book provides a number of practical designs which utilize. a range things as fiber optics, ultra bright LEDs and passive IR detectors etc.
-- While many of these designs are not in the "dead simple" category, they should be within the capabilities of anyone with a reasonable amount of experience at electronics construction and some of the more simple designs are suitable for beginners.
PREFACE
As little as fifteen to twenty years ago [as of 1987] the range of opto-electric devices available to the amateur electronics enthusiast was strictly limited. There were cadmium sulphide photoresistors, one or two phototransistors, but apart from a few other devices such as cathode ray tubes and "magic-eye" tuning indicators, that was about it. Things have changed quite radically since those days, and throughout the seventies and eighties there has been a procession of new opto-electric devices, including such things as light emitting diodes, liquid crystal displays of varying degrees of complexity, and sensors of various types.
These devices represent one of the most interesting aspects of modern electronics and many are worth trying out purely for their interest value. On the other hand, they mostly have as much practical application as play value, and are not just examples of the common phenomenon of clever technology in search of practical applications. They are consequently of interest to both the experimenter and those who are looking for solutions to practical problems.
This guide designs which utilize a range of modern opto-electric devices, including such things as fiber optic devices, ultra-bright light emitting diodes and passive infrared detectors. While many of these designs are not in the "dead simple" category, they should be within the capabilities of anyone with a certain amount of experience at electronics construction, and one or two of the more simple designs are suitable for beginners.
