Title: (EN) METHOD FOR CAPTURING A HEAT PATTERN
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.
