Abstract
A detector for detecting hot spots that includes an infrared sensor and a scanning component. The infrared sensor is fixedly mounted on a housing and is oriented to have a field of view of at least part of the region of interest. The scanning component is mounted in front of the infrared sensor and blocks most of the field of view of the infrared sensor and has a moving aperture that exposes the infrared sensor to a small area of the region at one time. The moving aperture provides a small instantaneous field of view and over time exposes the sensor to a much larger area.
