Abstract

L’invention concerne un système de spectroscopie (2) comprenant : - une chaîne de détection (8) configurée pour délivrer un signal de détection comportant des impulsions chacune représentative de la détection d’une particule ; et - une chaîne de traitement (10) configurée pour calculer un premier indicateur de détection, un deuxième indicateur de détection, un troisième indicateur de détection et un quatrième indicateur de détection représentatifs, respectivement, du résultat d’un test fréquentiste absolu unilatéral, d’un test fréquentiste relatif unilatéral, d’un test bayésien absolu et d’un test bayésien relatif appliqués à un spectre du signal de détection, et pour délivrer une information de détection de la présence d’au moins une source à détecter à partir du premier indicateur de détection, du deuxième indicateur de détection, du troisième indicateur de détection et du quatrième indicateur de détection. Figure pour l’abrégé : figure 1.The invention relates to a spectroscopy system (2) comprising: - a detection chain (8) configured to deliver a detection signal comprising pulses each representative of the detection of a particle; and - a processing chain (10) configured to calculate a first detection indicator, a second detection indicator, a third detection indicator and a fourth detection indicator representative, respectively, of the result of a unilateral absolute frequentist test, d 'a unilateral relative frequentist test, an absolute Bayesian test and a relative Bayesian test applied to a spectrum of the detection signal, and to deliver information for detecting the presence of at least one source to be detected from the first detection indicator, the second detection indicator, the third detection indicator and the fourth detection indicator. Figure for abstract: Figure 1.
