Abstract
Sensors using detector arrays (,) are intended for identifying events within a scene (,). A sensor comprising an array of pyroelectric infrared detectors (,) is mounted directly onto an integrated readout circuit (,) so that each of its elements is in electrical contact with one of the inputs to the readout circuit. The detector array (,) on its readout circuit (,) is positioned at the focus of an infrared transmitting lens (,) so that an image of a scene (,) is formed on the array. The readout circuit (,) and array (,) are enclosed in a package (,) which is connected via a circuit board (,) to a microprocessor (,). The microprocessor (,) and readout circuit (,) work together to detect the occurrence and position of events within a scene (,). Application examples are the detection and identification of location of flames or intruders within the field of view.
