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.

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： The present invention discloses a spectral measurement method via continuous light source and discrete light source, and a measurement instrument for non-invasive detection of human body tissue components. Said instrument includes an incident unit, a probe, a receiving unit and a data processing unit. Said composite spectral measurement method improves or strengthens the output light intensity at the wavelength that carries information of the target component within human body. It enables the spectral detection in the whole wavelength range, and thus significantly enhances the SNR of the detecting system. In the non-invasive detection instrument, light from both the continuous light source and discrete light source can be firstly selectively light-split by AOTF, or AOTF conducts light-splitting for the continuous light source, while the discrete light source LD is controlled by a spatial chopper. When data of the spectral curves achieved from said continuous light source and discrete light source are processed, data acquired under different measuring modes can be compared.

摘要： A dual side-hook structure is a hook unit with four hooks. The hook unit is latched on a horizontal, vertical or inclined rope or a long strip object without shifting to hang up an object without limitation in space. The hook unit includes positioning hooks on an upper end of the hook unit and hanging hooks on a lower end of the hook unit. A rope is enabled to pass through the positioning hooks or hanging hooks at two sides of the hook unit, and then the hook unit is secured on a fixed point on the rope without sliding freely. Edges of the positioning hooks and hanging hooks include abutting devices to prevent the rope from sliding out of the hook unit. The hook unit is positioned on a vertical rope by using the hanging hooks horizontally. The positioning hooks and the hanging hooks are used interchangeably. The entire hook unit is used very flexibly and versatilely without limitation in space, and is especially usable in a wild field, an outdoor area or a camping ground.

摘要： In a non-collinear type acousto-optic tunable filter, the incident angle of a source light beam L.sub.1 radiated from a light source 6 onto an acoustic medium 1 is set at an equivalence incident angle for which the wavelength .lambda..sub.i of the diffracted ordinary ray L.sub.3 and the wavelength .lambda..sub.i ' of the diffracted extraordinary ray L.sub.4 become approximately identical. Further, the diffracted ordinary ray L.sub.3 and the diffracted extraordinary ray L.sub.4 of the approximately identical wavelength are superposed, and the intensity of the superposed ray is detected. Consequently, spectrometry is performed based on the superposed diffracted ray having twice the intensity and a very sharp waveform, so that accurate spectroscopy can be made possible even if the intensity of the source light beam is low.
