Abstract (en)
[origin: WO9325926A1] Omnidirectional surveillance device characterized by optimal coverage of surrounding space. The device comprises detection units, each having a wide angle objective (01 to 06) associated with a two dimensional detector (D1 to D6). The invention is characterized in that the law of distortion of each wide angle objective is selected so that fields covered by two adjacent detection units, are contiguous. Application in the detection of infrared spectral band hot points such as missiles or jet engines.
