ABSTRACT:
A heat source locator (10) is disclosed having an elongated housing (11) in which is mounted a thermal detector (21), an infrared laser (22), a visible laser (23), and a light bar (25) all coupled directly or indirectly to the outputs of a semi-conductor (27). The thermal detector (21) is mounted within the housing (11) to sense a thermal input within a field of view FV along a central longitudinal axis LA. The infrared laser (22) is mounted within the housing (11) to transmit an infrared laser beam IRB generally parallel to and closely adjacent the longitudinal axis LA. The visible light (23) is mounted within the housing (11) to transmit a visible light laser beam VB generally parallel to and closely adjacent the longitudinal axis LA. With this construction, a target may be generally located by the thermal detector and the location pinpointed through an illumination of the target by one of the lasers.
