The imaging system for imaging field rays comprises a detection surface, a device for focusing the field rays with said detection surface, and a diaphragm. Said device comprises a Fresnel lens comprising a first dioptre, the non-plane surface of which, called the active zone, makes it possible to focus the field rays towards said detection surface, and said diaphragm allows controlled distribution of the field rays over said active zone.

Imaging system comprising a Fresnel lens

The invention relates to 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. According to the invention, the method comprises a step () of adjusting the recurrence of addressing the bolometer using the read circuit.
