IMAGE STABILISATION DEVICE Russian patent published in 2017 - IPC G02B23/18 G02B27/64 

FIELD: physics.

SUBSTANCE: image stabilisation device, which is part of the binoculars, includes a suspension mounted on the body of a two-stage cardan, a mobile inertial system, a magnetic spring and a vibration damper. The mobile inertial system contains a bracket fixed to the inner ring of the gimbal suspension, at one end of which a wrapping system of two prism blocks is attached, on the other end there is a caliper plate and a balancing weight. Also, the claimed device comprises two magnetic springs. One of these springs is made in the form of two magnetic contactors and corresponding two magnetic elements, which ensure the stabilization of the mobile inertial system in two mutually perpendicular planes. The amount of unbalance is not more than 0.1 g cm.

EFFECT: ensuring the identity of image stabilization characteristics under conditions of multidirectional disturbances.
