Abstract:
Compact detection device comprising:several detectors (4a, 4b, . . . ) adjacent to each other which form a detection plane (4); and a substrate assembly comprising: a first ceramic substrate (1); characterized in that it comprises: a second substrate (3) separated from the first ceramic substrate (1) and having electrical contacts on which the detectors are arranged, said second substrate and said first substrate being mechanically and electrically assembled together; means (10b) for polarizing the detection plane and means (10c) for processing signals detected by the detection plane, said means for polarizing and means for processing located in said first ceramic substrate; and a ground plane (2) placed between said first ceramic substrate and said second substrate to protect the detected signals from electromagnetic disturbances caused by the electronic noise generated by the device.
