DEVICE TRANSMITTING HORIZONTAL DIRECTION FROM ONE HORIZON TO ANOTHER Russian patent published in 2000 - IPC

FIELD: measurement technology, geodetic instrumentation. SUBSTANCE: device can be employed for transmission of horizontal direction, for instance, from ground surface to workings or to upper floors while engineering structures are erected. Device incorporates direction transmitter fabricated in the form of matrix of light sources optically coupled to direction receiver that includes telescope with vertical rotation axis and television camera with CCD matrix. Television camera is anchored on telescope so that its optical axis coincides with optical rotation axis of telescope. EFFECT: increased accuracy and reliability of measurements. 1 dwg
