Evaluation of the measurement accuracy with a photoelectric recorder relative to the unfolded laser plane

The article considers the issue of assessing the accuracy and efficiency of geodetic measurements using a laser beam sweep unit in a plane image and a patented photoelectric recorder with three photosensors located on a square opaque plate in a Z-shape, combined with three fiber-optic bundles at the entrance and connected to an electronic circuit with counters and indicators. A comparative analysis of photoelectric and optoelectronic recording devices, as well as methods of scanning the static and dynamic scanning of a laser beam into a plane image, is carried out, the main factors affecting the accuracy of measurements and methods of reducing their influence for a light surface of revolution - a “corrugated” plane in three coordinates of each A pent prism rotating around the axis of the laser beam was selected from the measurement points in the coverage area of the laser unfolded plane, as an optical element, the calculated data for evaluating the accuracy were obtained as applied to planning work and executive survey. During the construction and operation of industrial facilities, transport, hydro-technical and other structures, the main tasks of engineering and applied geodesy are: breakdown of axes, control of the installation of building structures in the design position, monitoring of precipitation and deformations, alignment of technological equipment, removal of red lines, etc. [1,2,3,4].
