AERO-PHOTO-TELEVISION DEVICE Russian patent published in 2007 - IPC G03B37/00 

FIELD: optics.

SUBSTANCE: aero-photo-television device comprises a body with objective and additional body serially mounted on optical axis, the additional body being mounted with possible rotation around the optical axis and made in form of hollow barrel facing the objective with its walls, which barrel is connected to the body by front supports along the edge of barrel. Back support is made in form of frictionless bearing, internal case of which is held in additional body, and external one - in the body of device. On internal walls of additional body, focusing mechanism is held, including focusing drive and executing mechanism in form of screw kinematic couples, consisting of driving screw and drive bushing, combining a plane with light-sensitive material with plane of best objective image with progressive movement of base with light-sensitive material along the optical axis. Front supports of additional body are made in form of immoveable overhanging supports, held on the body, in which rollers are held which interact with additional body, and internal case of back support is held in the bottom of additional body on optical axis. Also, optic-electronic transformer is introduced, on photo-receiving area of which a plane with light-sensitive material is positioned. Optic-electronic transformer is rigidly held on the base and mounted on optical axis in additional body by means of guiding axes, each one of which is rigidly fastened on the base and interacts with rollers, positioned in immobile overhanging supports on internal walls of additional body.

EFFECT: increased precision of focusing, increased stability of best image plane position, high quality of pictures.
