    • 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.

    • A measuring beam is incident upon a triangular cell storing a liquid sample, and transmitted light thereof is received by a linear sensor so that both transmitted light intensity and a position of the beam are detected. A refractive index calculating part calculates refractive indices from the position detected by the linear sensor, while an absorbance calculating part calculates absorbance values dependent on component concentration values correcting influence by transmittance change at the triangular cell through the transmitted light intensity values and the refractive indices of the sample calculated at the refractive index calculating part. A component concentration calculating part performs a multivariate analytical operation on the basis of the absorbance values dependent on the component concentration values at a plurality of measuring wavelengths calculated at the absorbance calculating part.
    • 测量光束入射在存储液体样品的三角形单元上,并且其透射光被线性传感器接收,从而检测透射光强度和光束位置。 折射率计算部分从由线性传感器检测的位置计算折射率,而吸光度计算部分通过透射光强度值和透射光强度值来计算依赖于三角形单元的透射率变化校正影响的成分浓度值的吸光度值, 在折射率计算部分计算的样本。 成分浓度计算部根据在吸光度计算部计算出的多个测定波长的成分浓度值的吸光度值,进行多变量分析。
