    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: A mass spectrometry system includes a sample holder provided in a vacuum changer and on which a sample is disposed, an irradiator configured to perform sputtering or ionization on the sample, an analyzer configured to analyze an ionized sample generated from the sample by the irradiator, and a controller configured to control the irradiator or the analyzer and perform a first process and a second process. The first process is to determine position information of materials in the sample by irradiating a laser or ion beam to a portion of the sample, and the second process is to irradiate a laser or ion beam of a first output value to another portion of the sample in a section in which the materials in the sample change and irradiate a laser or ion beam of a second output value in other sections.
