Title (EN) METHOD FOR CAPTURING A HEAT PATTERN
(FR) PROCEDE DE CAPTURE DE MOTIF THERMIQUE
Abstract:
(EN) Method for capturing a heat pattern with a sensor including a plurality of pixels each comprising a heat-sensitive measuring element, the sensor comprising an element for heating the measuring element, the method including carrying out the following steps for each pixel: a first heating step (202) in which a first amount of heating power is dissipated in the measuring element; a first step (204) of measuring the heat pattern, comprising a first read-out of the heat-sensitive measuring element, after a first delay time; a second heating step (206) in which a second amount of heating power is dissipated in the measuring element; a second step (208) of measuring the heat pattern, comprising a second read-out after a second delay time; and wherein the first amount of power is different from the second amount of power and/or the length of the first delay time is different from that of the second delay time.
(FR) Procédé de capture d'un motif thermique par un capteur comportant plusieurs pixels comprenant chacun un élément de mesure thermosensible, le capteur comprenant un élément chauffant de l'élément de mesure, comportant la mise en œuvre des étapes suivantes pour chaque pixel : premier chauffage (202) dissipant une première puissance de chauffage dans l'élément de mesure; première mesure (204) du motif thermique, comprenant une première lecture de l'élément de mesure thermosensible après un premier temps d'attente; deuxième chauffage (206) dissipant une deuxième puissance de chauffage dans l'élément de mesure; deuxième mesure (208) du motif thermique, comprenant une deuxième lecture après un deuxième temps d'attente; et dans lequel la valeur de la première puissance est différente de celle de la deuxième puissance et/ou la valeur du premier temps d'attente est différente de celle du deuxième temps d'attente.
