The complete guide to photodetection

Today's optoelectronic devices rely on accurate detection of light sources across the spectrum. This comprehensive guide surveys single-point devices and their image counterparts covering the range from UV to far IR. Basic operations, performance parameters, and special features are presented in the context of application circuits. Special attention is given to issues of sensitivity and noise limits. The devices surveyed include:

  • Photomultipliers
  • Semiconductors, photodiodes, avalanche devices, and phototransistors
  • Thermal devices and solar cells
  • Image detectors and CCDs

Concluding chapters deal with coherent detection and advanced techniques, while appendices offer convenient reference materials for key principles. Photodetectors: Devices, Circuits, and Applications is a useful reference for working engineers and an ideal sourcebook for university-level courses.
