Abstract
A temperature detection system for detecting relative or absolute temperatures of objects in a monitored area has at least one infrared (IR) detector and at least one optical element for directing IR radiation within a detector field of view onto the infrared detector. A scanning system is configured to produce relative movement between the optical element and the IR detector such that the detector field of view is scanned across a monitored area to receive IR radiation from objects in the monitored area. A signal processing module for receiving the detector output signal is configured to produce an output profile of the relative temperatures of objects in the monitored area. The IR detector may be a pyroelectric detector.
