Understanding Noise In Pyroelectric IR Detectors

Pyroelectric detectors are used in many types of IR detection applications where the key to the performance is the signal-to-noise ratio of the sensing element or detector. Since pyroelectric detectors are high output thermal devices, the noise output is typically the limiting item to their performance. This application note discusses the various sources of noise in these devices and how it can affect the performance in each application.
