The proposed device for checking the accuracy of the position of an engineering structure consists of several modules. Each module contains a source of optical radiation that propagates in two mutually opposite directions, a mulielement photodetector, two lenses, fiber lightguides, and diaphragms. The photodetector and the lenses form two digital optoelectronic chambers with the optical axes that are arranged in opposite directions. The elements of the photodetector are arranged in the plane is perpendicular to the plane that passes through the optical axes of the optoelectronic chambers and the axes of the diaphragms of the optical radiation source.
