More Information
Summary:Double band electromagnetic radiation detection device comprising a spiral antenna for the low frequency (8), obtained from a modification of the areas of a fresnel lens, and at least one high frequency detector (9). In the central area of the low frequency antenna, the transducer element is placed as detector (1). The spiral antenna (8) acts as a diffraction element that focuses the high frequency radiation on its detection plane (6), in which one or more detectors are located. The detectors are connected to an external circuit to process the signal. This system allows electromagnetic radiation to be simultaneously detected in two widely separated bands in frequency. The system allows to maintain a single optical axis (4) for both bands and manufacture the detectors in the same device. The use of the diffractive element increases the signal obtained by the high frequency detector. (Machine-translation by Google Translate, not legally binding)
