DETECTOR OF AN OBJECT INCLINATION ANGLE Russian patent published in 2004 - IPC

FIELD: control and measuring equipment.

SUBSTANCE: the invention presents a detector of an object inclination angle and is dealt with the field of the control and measuring equipment, in particular with devices used for determination of objects spatial positions, as well as in geodesy, construction, mining, in the navigational systems to control mobile objects. The detector of inclination angle contains a sensor, a source and a receiver of optical emission, an analyzer, focusing, guiding and the receiving lenses, a fiber-optic cable connecting source and the receiver of the optical emission. The sensor is made in the form of a disk optical plate with the natural polarization encased in a holder with a load fixed to it from below. Center of gravity of the load is located on a prolongation of an optical axis of the disk optical plate. The disk optical plate is mounted with a capability of rotation around of the horizontal axis crossing the optical axis of the disk optical plate. The guiding and receiving lenses are located on the semi-circumferences on both sides of the disk optical plate on the radiuses, that are smaller than a radius of the disk optical plate with the total positive clearance not exceeding its width. The technical result consists in elimination of sensitivity of the detector to temperature drops, raise of accuracy of measurements.

EFFECT: the invention allows to remove sensitivity of the detector to drops of temperature and to increase accuracy of measurements.
