Abstract: A device and a method for measuring a time-resolved thermal image. An embodiment comprises an optical imaging unit comprising a camera and a probe light source, the optical imaging unit emitting a probe optical signal from the probe light source to a sample during a time-resolution time; a control unit for outputting a first trigger signal to the camera, outputting a driving signal to the probe light source such that the probe light source emits the probe light source to the sample during the time-resolution time, outputting a second trigger signal to a bias unit in an turn-on interval, and outputting no second trigger signal to the bias unit in a turn-off interval; and a bias unit for applying a bias signal generated on the basis of the second trigger signal in the turn-on interval to the sample, and applying no bias signal to the sample in the turn-off interval.
