Abstract:
An apparatus for measuring a concentration of a component of a target material, the apparatus comprising:a pumping light source for emitting light having a single wavelength having peak power of at least a predetermined value; a first wavelength conversion unit for converting light incident from the pumping light source into light having at least one discrete wavelength and outputting the converted light; a first beam splitting unit for splitting the converted light incident from the first wavelength conversion unit into light beams and directing a first light beam at the target material; a reference light generator for converting a second light beam generated by the splitting performed in the first beam splitting unit to be parallel, dividing the parallel light beam by wavelengths, and outputting the result of the division as reference light; a first collimating unit for converting light transmitted through the target material to be parallel and outputting the parallel light; a light intensity measuring unit for measuring the intensity of light incident from the first collimating unit and the intensity of the reference light, by wavelengths, using the reference light; and a concentration measuring unit for measuring the concentration of the component based on the intensities measured by the light intensity measuring unit by wavelengths.
