    摘要: An apparatus and method for optically measuring concentrations of components allow enhancement in measurement accuracy of concentration. The apparatus includes a cell, a light irradiator, a photodetector, and an arithmetic unit. The cell presents different optical path lengths at different locations and is to contain a sample therein. The light irradiator, which includes a variable-wavelength laser generator and a measuring system composed of convex lenses, outputs a collimated, enlarged laser beam, and makes the laser beam incident upon the cell. The photodetector comprises a multiplicity of photodetectors arranged in parallel to the surface of the cell, so that it can detect intensity of rays of transmitted light that have traveled over different optical path lengths at positions of an equal distance from the cell. The arithmetic unit, receiving a signal from the individual photodetectors, calculates concentrations of components in the sample based on optimum optical path lengths for different wavelengths and values of transmitted light at positions of the optimum optical path lengths, and further outputs calculation results.

    摘要: To project measuring light with good reproducibility onto the measuring part of a measured object so that measurement conditions can always be constant. An optical measuring apparatus is equipped with a spectroscopic analyzer that detects the spectral intensity of the reflected light of measuring light projected onto a human hand. Spectroscopic analyzer moves in the direction" of the X-axis, Y axis, and Z axis, and around the Z axis by a moving mechanism. During the registration of the measuring part of the human hand, a CCD camera takes a picture of the human hand, and the operator selects a part having a feature from the pattern of the taken image. During the spectrometry, the CCD camera again takes a picture of the human hand. The optical measuring apparatus then detects the registered feature part on the currently taken image, moves spectroscopic analyzer by moving mechanism, and projects measuring light onto the registered feature part.

    摘要: To secure a highly accurate measurement value of biological information with minimized variation by positioning a target part of a living body with good reproducibility and by positioning the target part of the living body easily with high reproducibility without pressing blood vessels in the living body. The concentration of a particular component in the living body is measured by the use of a transmitted or reflected spectrum obtained by projecting light onto the target part of the living body. A biological information measuring template 2 includes a shape memory medium 6 having a contact surface which, when the target part is pressed to the contact surface, undergoes change according to the shape of the target part, to thereby store the shape. The target part 1 of the living body is arranged at a store portion of the shape memory medium and is illuminated by light. The spectrum of light transmitted through or reflected from the target part 1 is arithmetically processed in an arithmetic control means 4 to calculate the concentration of the particular component in the living body, a result of calculation being outputted to an output unit 5.
