This invention relates to a method and apparatus for digitizing light measurements by computer control light source emission. The invention uses a Light Sensitive Device (LSD), such as for example a camera system containing a CMOS-or a CCD-image chip, to perform precise measurements by digitally controlling the light source output. A constant output value is obtained from the LSD such that any non-linearity and range limitation of the LSD output is circumvented. The measurement methods and system are applied to chemical test and analytes, which are used for diagnostic purposes. The method can be used to measure reflectance, transmittance, fluorescence and turbidity.

La présente invention concerne un procédé et un appareil de numérisation de mesures de lumière par commande informatique de l'émission d'une source de lumière. L'invention fait appel à un dispositif photosensible (LSD), tel que par exemple, un système de caméra contenant une puce vidéo CMOS ou DTC, pour effectuer des mesures précises par commande numérique de la sortie de source de lumière. Une valeur de sortie constante est obtenue à partir du LSD de sorte que toute non-linéarité et limitation de plage de la sortie du LSD est contournée. Lesdits procédés et ledit système sont appliqués à des essais et à des analytes chimiques, qui sont utilisés à des fins de diagnostic. Ledit procédé peut être utilisé pour mesurer la réflectance, la transmittance, la fluorescence et la turbidité.
