This volume from the Wiley Series in Pure and Applied Optics offers a comprehensive technical exploration of infrared detectors and their associated systems. The text systematically covers the fundamental principles of photon detection and thermal detection, including photoconductive, photovoltaic, and bolometric mechanisms.

Detailed discussions address material properties such as bandgap engineering, doping profiles, and absorption coefficients that directly affect detector responsivity and detectivity. The book also examines system-level design parameters: optical configurations, cooling requirements (both cryogenic and thermoelectric), signal processing circuits, and noise reduction techniques.

Readers will find thorough explanations of noise sources—Johnson noise, shot noise, 1/f noise—and how these limit system performance in real-world applications. Fabrication considerations are presented, covering semiconductor growth methods, device patterning, and packaging for durability across environmental conditions.

The text emphasizes the trade-offs between cost, sensitivity, speed, and operating wavelength, making it a practical reference for engineers and researchers. With its strong grounding in both theory and applied optics, this resource is well suited for graduate students and professionals working in remote sensing, thermal imaging, spectroscopy, and security systems.

The affordable price point—just over ten dollars—provides exceptional value for a technical monograph that typically costs significantly more, allowing institutions and individuals to access high-quality optical science content without a heavy investment.
