Photoelectric recorder for measuring deformations of buildings and hydraulic facilities

摘要

The article discusses the issue of improving the accuracy and efficiency of geodetic measurements by scanning a laser beam into a plane and a photoelectric recorder of deviations from a given plane, in which a cZ-shaped photo recorder with three photosensors is used as a photosensor, combined at the output with three fiber-optic nodes and connected to an electronic circuit with three counters. A variant of using solar photovoltaic cells installed on the surface of a photoelectric recorder is proposed.
