Abstract
A method for detecting infrared radiation includes the steps of: providing a resistive bolometer retina including a plurality of resistive bolometers suspended above a substrate of a bolometric detector; acquiring the infrared radiation by the resistive bolometer retina to produce a plurality of raw read signals provided by the bolometers; correcting a response dispersion of the resistive bolometers in the raw read signals using a gain table, each gain of the gain table being associated with a bolometer of the resistive bolometer retina.
