Patent ID: 8431901

Claim:
A method for controlling the resistance of a bolometer in a bolometer matrix of a sensor, said sensor comprising a circuit for reading said matrix which is capable of addressing said bolometer, wherein the method comprises a step of adjusting the recurrence of addressing the bolometer using the read circuit, wherein the adjustment step comprises: selecting by means of the read circuit a window of the bolometer matrix, said window including the bolometer and having a number of lines L smaller than the total number N of lines in the bolometer matrix; selecting by means of the read circuit a frame rate f frame such that f frame <f line /L and corresponding to the required recurrence of addressing, where f line is a predetermined line rate; and the recurrent reading by the read circuit at the frame rate f frame of the L lines in the window selected, at the predetermined line rate f line , so that the lower number of lines in the window produces a more frequent addressing of each line thereof and therefore an increase in the recurrence of addressing the bolometer.
