Abstract
Apparatus and method for measuring concentration of a component of target material including a pumping light source for emitting light; a first wavelength conversion unit for converting and outputting the light; a first beam splitting unit for splitting the converted light and directing a first light beam at the target material; a reference light generator for converting a second light beam to be parallel, dividing the parallel light beam by wavelengths, and outputting the result 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 from the first collimating unit and 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.
