Abstract
(EN)
Optical computing devices are disclosed. One exemplary optical computing device (300) includes an electromagnetic radiation source (308) configured to optically interact with a sample (306) and at least two integrated computational elements (302, 304). The at least two integrated computational elements are configured to produce optically interacted light (314) and further configured to be associated with a characteristic of the sample. The optical computing device further includes a first detector (316) arranged to receive the optically interacted light from the at least two integrated computational elements and thereby generate a first signal corresponding to the characteristic of the sample.

L'invention concerne des dispositifs de calcul optique. Un dispositif de calcul optique cité à titre d'exemple (300) comprend une source de rayonnements électromagnétiques (308) configurée pour interagir optiquement avec un échantillon (306) et au moins deux éléments de calcul intégrés (302, 304). Les deux éléments de calcul intégrés sont configurés pour produire une lumière ayant interagi optiquement (314), et en outre pour être associés à une caractéristique de l'échantillon. Le dispositif de calcul optique comprend en plus un premier détecteur (316) agencé pour recevoir la lumière ayant interagi optiquement provenant des deux éléments de calcul intégrés et pour générer ainsi un premier signal correspondant à la caractéristique de l'échantillon.
