摘要： Optical measurement that is optimum for improving spatial resolution is accomplished by making it possible to estimate a physical quantity of an object substance to be measured at any point on a subject. When any position to be evaluated, in an image shown in a window 1-1, is pointed and selected a mouse pointer 1-4, the value of the concentration or its change of the object substance at the point is displayed in the display area 1-7 of a window 1-3. The drawings represents an example in which one position is specified and there are two object substances to be measured. The value of the concentration or its change of each object substance to be measured is separately displayed.

摘要： In a mass spectrometer using a sonic spray ion source, a technique of controlling the density of droplets in a nebulized sample solution which is passed into a mass spectrometer at high vacuum to an appropriate value to thereby reduce analysis noises is disclosed. A sample solution in a sample solution injection unit 1 is introduced into a capillary 2 disposed in an ion source 6. A gas is introduced from a gas supply unit 4 by way of a gas pipe 5 into the ion source 6 and is caused to flow along the outer circumferential surface at the top end of the capillary 2 and is jetted out from the orifice 3 as a gas flow into atmospheric air. The sample solution jetted from the top end of the capillary 2 is ionized by the gas flow in the atmospheric air. Fine droplets or ions formed by the sonic spray method are collide against a diffuser 7, droplets and ions reduced for the density by the diffusion pass through the holes 8 disposed in the diffuser 7, and pass from the sample orifice 10 into a mass spectrometer 11 and mass analyzed. Provision of the diffuser 7 can suppress generation of analysis noises caused by the clustering phenomenon resulting from introduction of droplets or ions at high density into the mass spectrometer 11, thereby enabling to conduct analysis at high S/N ratio.

摘要： Light rays of a plurality of wavelengths which are modulated in intensity with a plurality of different frequencies are irradiated on a plurality of irradiation positions on the surface of a living body, and time-variable changes in living body transmitting light intensity levels corresponding to the respective wavelengths and the respective irradiation positions are measured at different positions on the surface Changes in concentration values of absorbers are determined from the living body transmitting light intensity levels and a measuring point is set on a perpendicular extending through an intermediate point between the incident point and each detection point to image a function of the living body. The measuring time is shortened by estimating fluctuation attributable to the living body, and a local change in hemodynamic movement can be measured by detecting light rays transmitting through the interior of the living body by light detection at two different sites (equidistant from the light incident point) on a subject and by separating only the local change in hemodynamic movement from an overall change in hemodynamic movement in the living body in accordance with a logarithmic difference between the two detection signals.
