発明の名称 (英語) OPTICAL MEASURING DEVICE, OPTICAL MEASURING METHOD, AND STORAGE MEDIUM STORING OPTICAL MEASUREMENT PROGRAM
発明の概要(英語) An optical measuring device and method for accurately measuring light absorbance of a deep layer tissue of a human body or a piece of fruit by correcting the adverse influence of the superficial layer and a storage medium storing an optical measurement program are disclosed. The optical measuring device has a probe composed of a light-emitting diode and two photodiodes. Light emitted from the light-emitting diode and passing through the superficial layer and the deep layer of a tissue is received by one of the photodiode, and light emitted from the light-emitting diode and passing through the superficial and deep layers of the tissue and traveling a distance in the deep layer different from the distance which the light received by the one photodiode travels is received by the other photodiode. A control unit computes the propagation coefficient in the medium where the light propagates from the intensities of the lights received by the photodiodes. An arithmetic expression is selected depending on the inputted thickness of the fat of the tissue, and the light absorbance coefficient of the muscle tissue is determined by the arithmetic expression according to the fat thickness and the spatial inclination. From the determined light absorbance coefficient, the hemoglobin concentration and the degree of oxygen saturation are determined.
