A light equipment irradiating a target with light adjusts light from a light source in a light source optical system and introduces the same into an acousto-optic device, for separating the same into its spectral components and modulating the same in the acousto-optic device. A condensing optical system condenses first order diffractive light outgoing from the acousto-optic device, so that an irradiation optical system irradiates a target with the same. A photodetection device comprises a photoreceiving part and a data processing part, so that the photoreceiving part converts a signal responsive to the fluctuation of modulated measuring light to a plurality of signals of different degrees of amplification simultaneously outputting same. The data processing part selects a non-saturated value of an amplifier or an A-D convertor while maintaining the largest degree of amplification from these signals, and lock-in processes same with a modulation frequency modulating the measuring light. A specific substance in a scattering substance can be non-invasively measured with high accuracy.

Method of and device for positioning a living body for biological

A concave urine collector is set under a front end portion of a stool body, so that urine can be collected in a bowl. Single fiber holes are set on a front end and a left side of the urine collector respectively, while condenser lenses for condensing light on the bowl side, an excitation light fiber member carrying excitation light from an excitation light source and a Raman light receiving fiber member for receiving Raman light are set in the fiber holes respectively. The excitation light fiber member is connected with the excitation light source, and the Raman light receiving fiber member communicates with a spectro-detector. A Raman signal separated into its spectral components detected by the spectro-detector is data-processed by a data processing part, and outputted from a data output part as a measurement result.

Urogenous component measuring apparatus for qualitatively/quantitatively

A light source pa light of a plurality of wavelengths of a near infrared region, and a spectroscopic part selects a wavelength subjected to absorption by lactic acid as a measuring wavelength from measuring light of a plurality of wavelengths emitted from the light source part. A probe comes into contact with an organism measuring portion and irradiates the organism measuring portion with the measuring light of the wavelength selected by the spectroscopic part, while a photoreceiving part detects transmitted/scattered light of the measuring light incident upon the organism measuring portion. A light signal detected by the photoreceiving part is converted to absorbance in a signal processing part, so that the concentration of lactic acid is calculated by a host computer serving as an arithmetic-control part and displayed on a display part. No reagent is required, while difference between lactic acid concentrations varied with measuring portions can also be noninvasively measured.
