Abstract

The invention discloses an optical fiber common point target used in a station-moving test process of an electronic theodolite and relates to the optical fiber public point target, which solves the problem that a measurement error is large because a hemisphere of the current common point target is needed to be rotated manually after the electronic theodolite is moved and the aiming difficulty of the electronic theodolite is high due to unavailable lamination. A luminous end of the optical fiber common point target used in the station-moving test process of the electronic theodolite is a spherical optical fiber; and the tail end of the optical fiber of which one end is spherical is contacted with a light output end of a luminous module. The optical fiber public point target is suitable for the station-moving test process of the electronic theodolite.

Description

technical field [0001] The invention relates to an optical fiber common point target. Background technique [0002] The spatial angle forward intersection measurement system composed of two electronic theodolites is one of the earliest and most widely used systems in the field of large-scale measurement. It is generally composed of electronic theodolites, reference rulers, communication interfaces, connection cables, and computers. When the size of the workpiece to be measured is large, the measuring instrument cannot measure all the elements to be measured at one position, or the workpiece to be measured is a rotating body, the "line of sight" of the instrument will be blocked by the workpiece itself, and the elements on the back of the workpiece cannot be measured. In both cases, it is necessary to relocate the electronic theodolite. [0003] Since the measurement process is based on the electronic theodolite's own coordinate system, that is, the instrument coordinate sys...
