FIELD: optics.
SUBSTANCE: invention relates to the field of optoelectronic equipment and concerns an automated device for connection to reverse plumb lines. Device includes lens focusing image on CCD matrix, in which each photosensitive element has its unique coordinates, microcontroller, rotary unit and a mirror prism. CCD matrix is designed to convert photon energy into a digital signal coming to the microcontroller and containing information on the coordinates of darkened pixels. Microcontroller is designed to calculate the required angle of rotation of the device depending on the incoming digital signal and transmission of the corresponding digital control signal to a rotary unit consisting of a step motor with a piezo-actuator. Mirror prism is made with dihedral angles at base equal to 45°.
EFFECT: technical result consists in improvement of accuracy of azimuth of plane removal by eliminating error of observer during instrument display in plane of reverse plumb lines.
