Abstract
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 in which a first amount of heating power is dissipated in the measuring element; a first step 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 in which a second amount of heating power is dissipated in the measuring element; a second step 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.
