Our optical sensors blocks family is composed of a number of various systems designed for target surveillance and observation of tactical fields. The optical sensors blocks can be integrated in surveillance or aiming systems. They include optical sensors for day and night surveillance, tracking and image fusion boards, other functions required by specific application. All these sensors are controlled by a specialized electronic board which ensures also communication with external devices as computers or multifunction displays. The thermal camera allows detection of thermal radiation from humans and vehicles in conditions of dust, rain, snow, fog and high umidity.
