Device for measuring the electromagnetic radiation of a radiating object

A device for measuring the electromagnetic radiation of a radiating object (10), comprising:

• a sealed box (20), impervious to electromagnetic radiation, extending in a longitudinal direction (L) and equipped with an opening adapted to allow said radiating object (10) to be measured to be housed in said box;
• means (13) for modulating the radiation of said radiating object;
• characterized in that it further comprises:
• means (12) for moving said radiating object (10) inside the sealed box (20) in the longitudinal direction (L) between a position, called proximal position, and a position, called distal position;
• a heat-sensitive film (14), heat-sensitive to the electromagnetic field, housed in said sealed box (20) and extending in a plane perpendicular to said longitudinal direction in the vicinity of said proximal position;
• a camera (16) housed at a longitudinal end of said sealed box (20), opposite said radiating object (10) to be measured relative to the heat-sensitive film (14), and configured to acquire images of said heat-sensitive film, with said heat-sensitive film (14) being arranged at the focal distance from said camera (16);
• means (18) for processing said images acquired by said camera (16) configured to provide a map of the electromagnetic field of said radiating object (10) picked up by said heat-sensitive film (4).
