MAKE OPTICAL MEASUREMENTS WITH MAXIMUM ACCURACY AND MINIMUM COST


Photo detection and measurement techniques are used by engineers and physicists to “characterize” optical devices and systems. Characterizing – numerically describing a device’s performance – is vital to the design and analysis of fiber optics, laser systems, and opto-electronic circuitry. As more and more of electronics are becoming opto-electronic (because light moves faster then electricity) the art of taking accurate, inexpensive optical measurements has become very important to EEs across the board.This is a practical engineering tutorial on making accurate and effective measurements without spending a fortune – by using equipment commonly available in labs and companies. It considers the full chain of equipment: photo detectors, amplifiers, LED sources, electronic drives, basic optics, interference screens, and data acquisition systems. MathCAD will be used for frequency plots throughout.

MAKE OPTICAL MEASUREMENTS WITH MAXIMUM ACCURACY AND MINIMUM COST

The "opto-electronics revolution" has made the art and science of making sensitive, accurate, and inexpensive optical measurements must-know information for legions of electronic engineers and research students. And there’s no faster or easier way to master photodetection and measurement techniques than with this hands-on tutorial written by a teacher with experience enough to know the questions you would ask.

A clear, easy-to-understand "rules-of-thumb" approach shows you how to make high-performance optical measurements by getting the fundamentals right, often with simple, inexpensive equipment commonly found in laboratories. It includes treatment of:
* Photodetectors
* Amplifiers
* LED sources
* Electronic modulation and demodulation
* Interference avoidance
* Data acquisition and basic DSP

You’ll also gain a firm understanding of noise-reduction techniques and the essentials of building-in speed, sensitivity,and stability. If you want to learn the secret of making sound optical measurements without expensive equipment, this is the one resource you shouldn’t work without.
