WAVE FRONT INCLINATION COMPENSATOR MECHANISM Russian patent published in 2013 - IPC G02B26/08 

FIELD: physics.

SUBSTANCE: mechanism has a plane-parallel circular plate mounted in a gimbal suspension, which is in form of a movable ring mounted in cylindrical hinges lying at diametrically opposite points thereof in a fixed base and rims of the plane-parallel circular plate, mounted in cylindrical hinges lying at diametrically opposite points of the movable ring such that the axes of the cylindrical hinges cross at the geometric centre of the plane-parallel circular plate at a right angle. Two stepped actuators are mounted on the fixed base such that one of them can interact with the movable ring at a point lying equidistant from its cylindrical hinges, and the second can interact with the rim of the plane-parallel circular plate at a point lying equidistant from its cylindrical hinges. Between the movable ring and the fixed base at a point diametrically opposite the installation of the stepped actuator, there is a compression spring, and a second compression spring lies between the base and the rim of the plane-parallel circular plate at a point diametrically opposite the installation of the second stepped actuator.

EFFECT: simple design of a wave front inclination compensator mechamism.
