Investigation of Factors Determining the Accuracy of Dual-channel LMS

When measuring, centering and adjusting large-scaled objects and equipment, an extremely large share is occupied by laser measuring systems. Of essential importance when measuring with these systems is the compliance of the accuracy parameters with the requirements imposed on the objects. In order to evaluate the metrological characteristics of the developed laser system, the present paper presents a study of the factors affecting the accuracy when measuring with it. The characteristics of the photodetector and the photodetector block and the structure of the laser beams of the system were investigated. A functional check of the consistency of the individual modules of the receiving unit was also made.
