Claim:
1. A system comprising: a device under test (DUT); a thermal camera configured to produce a plurality of thermal images of the DUT; a computer device in data communication with the thermal camera, the computer device comprising a processing device and an output device; and a control unit in data communication with the DUT and at least one of the thermal camera or the processing device; wherein the DUT is caused to run in a first operational state in response to a first framing signal that is generated by the thermal camera to indicate a first timing of a first frame sequence of the thermal camera, and wherein the processing device is configured to acquire a first thermal image of the DUT from the thermal camera based on the first framing signal, wherein the DUT is caused to run in a second operational state in response to a second framing signal that is generated by the thermal camera to indicate a second timing of a second frame sequence of the thermal camera, and wherein the processing device is configured to acquire a second thermal image of the DUT from the thermal camera based on the second framing signal, and wherein the processing device is configured to generate at least one output image based on a difference between the first thermal image and the second thermal image.
