Abstract: Disclosed are a multi-mode thermal imaging device and an operation method thereof. According to an embodiment of the present invention, in a first mode, a first sample is scanned with an optical signal from a light source, signals reflected from the first sample by the scanning are detected separately for each wavelength, a reflectance change spectrum according to the wavelength is derived on the basis of the signals detected separately for each wavelength, a wavelength is selected on the basis of the derived reflectance change spectrum, and a thermal image of the first sample is obtained, through a filter, by detecting an optical signal limited to the selected wavelength from among the signals reflected from the first sample. In a second mode, thermal radiation of a second sample is detected to obtain a thermal image of the second sample.

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.
