Abstract: Disclosed is a temperature distribution measuring device for measuring the temperature distribution or the heat generation distribution in a sample. An embodiment collects a reflection signal the reflectivity of which changes on the basis of a bias signal applied to a sample, detects a signal of interest, which has been reflected from a region of interest in the sample, from the reflected signal, converts the signal of interest to a frequency range signal, calculates the relative amount of change in reflectivity of the sample by using a direct current component extracted on the basis of filtering of the frequency range signal and a frequency component of the bias signal, and acquires a thermal image of the sample on the basis of the relative amount of change in reflectivity.

Abstract: A device and a method for measuring a time-resolved thermal image are disclosed. 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. The camera generates a first reflection image of the sample by using a signal reflected from the sample when the probe optical signal is emitted to the sample during the time-resolution time in the turn-on interval. The camera generates a second reflection image of the sample by using a signal reflected from the sample when the probe optical signal is emitted to the sample during the time-resolution time in the turn-off interval. The control unit generates a time-resolved thermoreflectance image of the sample on the basis of the generated first and second reflection images.
