Abstract
An active infrared sensor may include an imaging infrared sensor to provide an output signal conveying time-sequential infrared images of a scene which includes a subject, a beam generator to generate a millimeter wave energy beam, and a processor. An initial infrared image of the scene may be stored in a memory. After storing the initial infrared image, the beam generator may illuminate the subject with the millimeter wave energy beam. A temperature change across the subject due to the millimeter wave energy beam may be estimated based on the output signal and the stored initial infrared image. The beam generator may stop illuminating the subject when a highest temperature change across the subject is at least equal to a predetermined temperature change limit.
