Claims23
Device for detecting infrared radiation comprising a resistive imaging bolometer, able to be electrically connected to a circuit for measuring a resistance of the bolometer, wherein it comprises means for controlling the resistance of imaging bolometer by injecting current into the bolometer.
System for detecting infrared radiation comprising an array of at least one row of devices, each comprising:
- a resistive imaging bolometer;
- and a measuring circuit capable of being electrically connected to the imaging bolometer in order to read a resistance of the bolometer,
- wherein each device comprises means for controlling the resistance of imaging bolometer by injecting current into the bolometer.
Method for reading a resistive imaging bolometer in an array of bolometers that constitutes a system for detecting infrared radiation in which the resistance of the bolometer is adjusted to a predetermined resistance value that is common to all the bolometers in the array at least once every read cycle of the bolometer by injecting current into it.
