Title (EN) APPARATUS AND METHOD OF GENERATING PH OF SUBJECT FROM AT LEAST THREE WAVELENGTHS
(FR) APPAREIL ET PROCÉDÉ DE GÉNÉRATION DE PH DE SUJET À PARTIR D'AU MOINS TROIS LONGUEURS D'ONDE
Abstract:
(EN) An apparatus obtaining a p H level of a tissue comprises an array of at least three optical sensors configured to absorb light shined on the tissue and thereby obtain at least three electronic digital signals, wherein the first electronic signal A1(X,t) represents the light absorbed by the tissue in location X = (X,Y,Z) at time t and at wavelength L1, and similarly the second and third electronic signal A2(X,t) and A3(X,t), and a finite absorption range of the three wavelength L1, L2 and L3 is such that 0 <= A3(X,t) <= A2(X,t) < A1(X,t); and an electronic processing unit receives the signals and applies an ordered monotone function, F1, to the tissue, to spatial temporal information of each wavelength, F1 used by a transfer function for presentation as a Look Up Table connecting actual values computed by F1 and an actual pH of the tissue in location X at time t.
(FR) L'invention porte sur un appareil permettant d'obtenir un niveau de pH d'un tissu comprenant un réseau d'au moins trois capteurs optiques conçus pour absorber la lumière projetée sur le tissu et obtenir ainsi au moins trois signaux numériques électroniques, le premier signal électronique A1(X,t) représentant la lumière absorbée par le tissu à l'emplacement X = (X,Y,Z) au temps t et à la longueur d'onde L1, et de façon similaire les deuxième et troisième signaux électroniques A2(X,t) et A3(X,t), et une plage d'absorption finie des trois longueurs d'onde L1, L2 et L3 étant tels que 0 <= A3(X,t) < = A2(X,t) < A1(X,t) ; et une unité de traitement électronique recevant les signaux et appliquant une fonction monotone sélectionnée, F1, au tissu, à des informations temporelles spatiales de chaque longueur d'onde, F1 étant utilisée par une fonction de transfert en vue d'une présentation sur une palette reliant des valeurs réelles calculées par F1 et un pH réel du tissu à l'emplacement X au moment t.
