A theodolite is a precision measuring instrument widely used in engineering surveying, topographic mapping, and construction. It is primarily employed to measure horizontal and vertical angles, providing accurate angular data for engineering design, construction layout, and topographic mapping. The structure of a theodolite mainly includes a telescope, horizontal graduated circle, vertical graduated circle, and base. By aiming at the target through the telescope and reading the graduated circles, the angular position of the target point can be precisely measured. Depending on accuracy and functionality, theodolites are divided into optical theodolites and electronic theodolites. Optical theodolites rely on optical principles to read angles, with intuitive operation suitable for various measurement scenarios. Electronic theodolites, on the other hand, integrate electronic technology to achieve automatic reading and data storage, enhancing measurement efficiency and accuracy. Whether for large-scale infrastructure construction or precise topographic mapping, the theodolite plays an essential role and is an indispensable tool in surveying work.
