FULL-RANGE CALIBRATION APPARATUS FOR A SPECTROMETER FOR ANALYSIS OF THE LIGHT SPECTRUM, AND METHOD FOR ACQUIRING INFORMATION USING THE APPARATUS

摘要

The present invention relates to a full-range calibration apparatus for a spectrometer for analysis of the light spectrum and to a method for acquiring information using the apparatus. Using a wavelength scan filter, the full-range calibration apparatus scans light generated by an input light source and selects a specific wavelength, enables the spectrometer to sense a signal of pixel information from light of the selected specific wavelength through a camera, enables a light spectrum analyzer to perform analysis on the light of the selected specific wavelength so as to acquire optical spectrum wavelength information, and performs one-to-one mapping between the thus-acquired optical spectrum wavelength information and the aforementioned sensed pixel information, thereby acquiring wavelength information and pixel information in a simpler and more accurate manner than complicated conventional methods. Therefore, the apparatus of the present invention can be used with a variety of light sources, and is thus highly marketable.
