Abstract: Disclosed are heat management method, and system, and computer program product that include at least one optical strain gauge that is mounted on a printed board in proximity to an object being monitored for temperature changes. Power for controlling heat to the object is modified in response to changes in the optical reference signal of the gauge, whereby such changes are correlated to the rate of strain change in the object as measured relative to predefined temperature changes of the object being monitored.
