OPTICAL MEASURING APPARATUS AND OPTICAL MEASURING METHOD FOR BIO MATERIAL AND CHEMICAL SUBSTANCE

摘要

PPROBLEM TO BE SOLVED: To provide an optical measuring apparatus and an optical measuring method, which can detect and qualitatively/quantitatively analyze bio materials contained in living tissues or blood and chemical substances entering a body and attaching to its inside, rapidly, accurately and noninvasively in infrared and near-infrared regions. PSOLUTION: The noninvasive optical measuring apparatus for the bio materials or the like, which can qualitatively/quantitatively analyze the bio materials contained in the living tissues or the blood, includes at least an irradiating means (1) which irradiates an object to be measured with infrared and near-infrared light having wavelength ranging from 800 to 4,000 nm output from an acoustooptic adjustable oscillating filter, and a photoelectric converting means (2) which receives light being projected in above irradiation process and transmitted through or reflected by the object to be measured, by using a photosensitive element composed of one or more kinds of photosensitive materials having a spectral sensitivity characteristic in which the maximum value exists in a range of wavelength not longer than 2,000 nm, and photoelectrically converts the outputs in order to obtain absorbance spectra.
