BINOCULAR DOUBLE-CHANNEL DEVICE FOR DAYLIGHT AND NIGHT STEREOSCOPIC OBSERVATION Russian patent published in 2000 - IPC

FIELD: optical instruments. SUBSTANCE: device has two branches, which are joined by means of hinge. Each branch consists of housing, lens and eye piece. In addition device has mobile and stationary members of light beam deviation unit. Each branch of device has electronic-optical converter of images. Mobile member of light beam deviation unit is designed as base, which carries two deflectors of optical beams. First deflector is located between lens and electronic-optical converter of images. Second deflectors is located between electronic-optical converter of images and eyepiece. Both deflectors are mounted for joint movement. Base is connected to channel switching drum, which is mounted in housing of branch on axis, which is parallel to hinge axle. Cylindrical surface of drum has curve-shaped groove. Hinge axle carries additional hinge, which is equipped with leads, each of which passes through guiding groove of housing of its branch and is connected to curve-shaped groove of channel switching drum. EFFECT: decreased weight and size, synchronous switching of channels in both branches. 5 cl, 2 dwg
