<p>A thermal detecting device (20) for sensing temperature at multiple locations (62, 64) proximate to the detecting device is provided. The detecting device (20) has a pair of infrared detectors (32, 34) each configured to measure temperature of two locations (62, 64) by receiving infrared energy of the two locations (62, 64). A housing (22) encloses the pair of infrared detectors (32, 34). The housing (22) is configured with an aperture (24) to allow the infrared energy of the two locations (62, 64) to be received by the pair of infrared detectors (32, 34). A reflective mirror or two mirrors (30A, 30B) focus the infrared energy of the two locations (62, 64) towards the pair of infrared detectors (32, 34). The detecting device (20) may be configured to determine if there is a temperature differential at a location as the housing (22) moves with respect to the location.</p> |
