Pyroelectric Infrared Detectors Stephen G. Porter This little book introduces pyroelectricity and pyroelectric detectors for students, scientists, engineers, and others with a basic grounding in physics and mathematics. It covers the basic concepts of the pyroelectric effect and includes a chapter on pyroelectric materials. It discusses device physics, including black-body radiation and infrared absorption. Performance modelling of pyroelectric detectors is covered in detail leading to the derivation of performance figures of merit. The chapter on applications covers sensors, monitors, radiometers, and thermal imagers, with a brief section comparing pyroelectrics with alternative technologies.
