A method and apparatus for preventing the occurrence of false responses in optical detection devices, which are sensitive to changes or fluctuations in optical radiation emitted from a source. The following steps are carried out: a) receiving optical radiation emitted by a source; b) selecting a predetermined range of wavelengths; c) detecting changes in the received optical flux and deriving therefrom a signal having time series data (signal traces) at the detector output; d) analyzing the detected signal for its chaotic (i.e. aperiodic) behaviour by establishing the associated fractal dimension of the signal and using the existence of this fractal property of the said time series data of the optical radiation emitted by the said source to discriminate against those sources of fluctuating optical radiation which are periodic or intermittent; and e) only providing a response at the output of the optical detection device in case of chaotic behaviour of the source.
Procédé (et appareil associé) de prévention des réponses erronées de systèmes optiques de détection, sensibles à des variations ou fluctuations du rayonnement optique d'une source, dont les étapes sont: a) réception du rayonnement émanant de la source; b) sélection d'une plage prédéterminée de longueurs d'ondes; c) détection des variations du flux de rayonnement dont on tire un chronogramme du signal (trace du signal) à la sortie du capteur; d) analyse du signal détecté pour y déceler un comportement chaotique (p. ex. apériodique) en établissant la dimension fractale associée au signal et en utilisant ladite dimension fractale des données chronologiques du rayonnement de la source de rayonnement optique pour distinguer cette dernière des sources périodiques ou intermittentes de rayonnement optique fluctuant; et e) ne fournir de réponse à la sortie du détecteur optique qu'en cas de comportement chaotique de la source.
