TY - JOUR AB - A low cost two dimensional pyroelectric array technology has been developed, together with advanced signal processing algorithms. This enables the availability of intelligent passive infrared detector systems for surveillance, counting, and related applications. The technology has also made possible for the first time a truly affordable low‐resolution thermal imager for condition monitoring, plant maintenance, and process control.
