Abstract: The invention relates to a spectrometer ( 1 ) comprising a dispersive element of a light beam formed of a set of spectral components, the dispersive element generating spatial dispersion of the spectral components in the form of a dispersion spectrum ( 6 ) spatially spread, at least one photon detector ( 5, 52 ) comprising at least one detection element ( 51 ) being provided at one point of said dispersion. According to the invention, a matrix optical electromechanical device ( 3 ) is provided between the dispersive element and the detector in the dispersion spectrum, said electromechanical device being formed of a matrix of optical elements, each of the optical elements being able to send back a portion of the dispersion spectrum according to at least two directions in relation to a control signal, in order to enable the selection of at least one sub-assembly of the spectrum for said detection element. A method and an application of the spectrometer are claimed.

Abstract: Miniaturized spectrometer in the form of a probe for determining ingredients of a gaseous or liquid fluid with a light source and a spectrometer, at least one measurement beam, and at least one reference beam. Light from the light source is optionally fanned out and focused, by at least one optical lens, in an essentially parallel beam. At least one measurement beam is passed through a light transparent window from the probe into the fluid being investigated and through an additional light transparent window back in to the probe, and at least one reference beam is guided in the probe interior. A collecting optics device, comprising at least one lens, diverts the beams to the impingement point of the light guide or the inlet of the spectrometer, and a beam selector in the area of the collecting optics device passes through one of the partial beams and interrupts all the others.

Abstract: A system for predicting blood constituent values in a patient includes a remote wireless non-invasive spectral device, the remote wireless non-invasive spectral device generating a spectral scan of a body part of the patient. Also included are a remote invasive device and a central processing device. The remote invasive device generates a constituent value for the patient, while the central processing device predicts a blood constituent value for the patient based upon the spectral scan and the constituent value.

Abstract: An optical system for measuring an optical density of a sample in which homogeneity of light employed for measuring the density thereof is secured by including optical information upon a light source uniformly inside a measurement space about an optical axis therein even if the fluctuation occur in the light source in the system. A beam of light emitted from the light source and then focused on an interference filter is transformed into a parallel light through a collimator lens, and the parallel light is then split into two parallel pencils of light by an optical mask. The parallel light uniformly includes the optical information upon the light source. A reference cell is placed in a first split parallel pencil of light, and a sample cell is placed in a second split parallel pencil of light. The lights that have passed through the two cells are focused on an optical receiver by a focusing lens.

Abstract: A flicker photometer comprises generating means (1, 8, 4) for generating two beams of light of different colours. Both beams are directed to a viewing means (190), and a subject can vary the intensity of light from one beam relative to the other. The colour of the light seen by the subject is caused to alternate. The performance of the photometer is improved by screens which scatter light before it reaches the subject. A first of the screens (186, 188) reflects light from one beam, whilst a second screen (b) is translucent, and thus transmits light from the other. If light of wavelengths to which the eye is less sensitive is passed through the second screen, whilst light of a wavelength to which the eye is more sensitive passes through the first screen, the screens help to make it practicable for the generating means to use a single lamp (1) to produce the light for both beams.

Abstract: A method and apparatus for controlling the reciprocation of a movable mirror of an interferometer used in an interferometric spectrophotometer are disclosed, wherein a frequency dividing ratio corresponding to a desired reciprocating speed of the movable mirror is set and then a pulse signal from an oscillator is divided at the frequency dividing ratio for producing a frequency-divided signal which in turn is compared with an interference signal from a control interferometer to produce an error signal for controlling the reciprocating speed of the movable mirror based on this error signal until the desired reciprocating speed is reached. Preferably, the frequency dividing ratio can be varied by a central processing unit, for example, so that the user is able to freely change the reciprocating speed of the movable mirror to conform to the type of a detector used, thereby enabling a measurement under optimum conditions.
