ELECTROMAGNETIC DETECTION DEVICE INCLUDING A RESISTIVE IMAGING BOLOMETER, SYSTEM INCLUDING A MATRIX OF SUCH BOLOMETERS, AND PROCESS FOR READING AN IMAGING BOLOMETER IN SUCH A SYSTEM

摘要

The invention relates to a device for the detection of electromagnetic radiation comprising an electromagnetic radiation sensitive resistive bolometer (12) to be detected, intended to be electrically connected to a signal forming circuit (10), and a bolometer. resistive reference (26) electrically associated with the imaging bolometer (12), such that the current flowing through the reference bolometer (26) is removed from the current flowing through the imaging bolometer (12). According to the invention, this device comprises means (40) for controlling the resistance of the reference bolometer by injecting current thereinto.
