ALL-AROUND SURVEILLANCE DEVICE Russian patent published in 2017 - IPC G01S3/78 

FIELD: electronics.

SUBSTANCE: invention relates to electro-optical instrument making and can be used for detecting and video recording air and ground objects, as well as in active and passive location. Said result is achieved due to the fact, that the all-around surveillance device comprises an azimuthal platform with a drive and an angle transducer, on which there are electro-optical devices and thermal imagers, providing all-round surveillance and video recording air and ground objects, as well as instruments of active and passive location while continuous all-round surveillance with increased time of exposure of the observed space, increased time of exposure is ensured by accelerated displacement of a prism of the optical compensator into the beginning of the zone of working angles with the help of a intermittent motion mechanism, made, for example, in the form of a Maltese mechanism and a differential gear in the form of a planetary mechanism, beginning and end of image exposure of the observed space is synchronized with the beginning and end of the zone of working angles of the optical compensator.

EFFECT: technical result is increased time of exposure of the observed space.
