    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.
