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. 1. A multi-mode thermal imaging device , comprising:a microscope;a spectroscope;a controller; andan infrared thermal imager,wherein the multi-mode thermal imaging device operates in one of multiple modes,wherein in a first mode among the multiple modes, the microscope scans a first sample with an optical signal from a light source, the spectroscope detects signals reflected from the first sample by separating them for each wavelength, and the controller derives a reflectance change spectrum according to the wavelength on the basis of the signals detected separately for each wavelength, selects a wavelength on the basis of the derived reflectance change spectrum, and obtains a thermal image of the first sample by detecting, through a filter, an optical signal limited to the selected wavelength from among the signals reflected from the first sample, andwherein in a second mode among the multiple modes, the infrared thermal imager detects thermal radiation of a second sample to obtain a thermal image of the second sample.2. The multi-mode thermal imaging device of claim 1 , wherein the light source corresponds to a white light source ...
