Description

drawing bone), which are the prisms of the inner internal reflection with spherical refracting output surfaces 2 of one refraction (ft)). symmetrically located with respect to their centers of curvature 3 and 4 that lie on the line of intersection of the plane of the paralactic: tla ne; normal to its plane from the optical axis of the lens at a distance equal to half of the base B of the entrance pupils 5; volume 6; the oculi 7 with reflectors 8 (conventionally rotated into the plane of the drawing) are rigidly interconnected with the possibility of movement along the optical axis of the lens and have a kinematic connection with a gear ratio equal to two, for example, by means of lath gear 9-12 from. steering wheel 13 with movable prisms (angle mirrors) 14.. The device is applied as follows. Before the start of the operation, it is fixed above the nose with a spectacle frame. In this case, the plane of the exit pupils 15 is aligned with the plane of the pupils of the surgeon's eyes. The coaxiality of the eyes of the eyes and the exit pupils 15 of the device is ensured by rotating the handwheel 13 with the treads 9 and 10, which engage with the rail 11 of the eyeglass rim 7 with a gear ratio of two and the gear rail of the corner mirror 14, equal to one. Thus, when the basis B is changed between the exit points of the ara 1 and 15, the angle mirror 14 moves two times slower than the ocular 7 with the reflector 8 in the same direction, so that the focusing of the device on the observed object O is not disturbed. The surgeon does not experience the phenomenon of diplopia when approaching object O or moving away from it within the limits of the depth of sharply visible space, since the axis of symmetry of the RO device passing through the paraparatactic angle x and the basis gray line is a single physical (optical) axis of interaction two spheres

652519 This technical solution allows: using a standard spectacle frame as a carrier, which significantly reduces weight and size, reduces cost and improves operating conditions, changes the basis between the exit pupils without disturbing the focus and maintaining the parallax angle between the axes of the objectives monocovers, which expands the depth of accommodation without the appearance of diplopia and, accordingly, improves the working conditions of the surgeon. change the distance between the exit pupils in accordance with the eye base of the observer without the use of well-known additional devices that complicate the design, increasing the size and weight. Stereoscopic device for observing an object, containing an entrance pupil in each optical channel, a fixed prism in front of the lens, a movable prism installed between the lens and an ocular with a reflector, and a drive, characterized in that, in order to increase the depth of accommodation without diplopia, in it, fixed priams are made in the direction of full internal reflection prisms connected with each other with an output spherical surface whose center is located at a distance from the optical axis bektiva equal to half of the basis of the input pupil, and ocular reflector are rigidly coupled together and are movable prism with a kinematic linkage with the transmission ratio equal to two.
