OPTOELECTRONIC SURVEILLANCE SYSTEM WITH VARIABLE OPTICAL FIELD

摘要

The invention relates to an optoelectronic surveillance system, which comprises an acquisition unit (1) including at least one sensor (2) mounted behind a zoom (3) having a group of mobile lenses (4) at the front and a group of stationary lenses (5) at the rear, defining at least one first space (6) in convergent rays, and a control unit (10) connected to the acquisition unit (1) and to a rotary optical element (11) arranged such as to rotate about a first axis (A1) and secured to a drive member controlled by the control unit (10) in order to modify a field perceived by the sensor (2) regardless of a movement of the acquisition unit (1) about the first axis. The optical element is a first transparent plate mounted in the first space (6) such as to rotate about the first axis, and the drive member is arranged such as to rotate the first plate in two opposite directions.
