Laser Based Technology of Monitoring the Dynamic Displacements of Objects Spatial Structures

摘要

The article describes the method of creating a laser measuring system to control the level of dynamic displacements of spatial structures of objects. In the considered system for vibration control, the creation of a laser vibrometer has been described and the advantages of its use have been substantiated. Using the method of laser sensing allows monitoring of complex technological objects under the influence of various disturbing factors (man-made and natural). Remote sensing in the area of vibration of structures can be carried out in two ways: the method of processing reflected laser beam or the method of direct projection sounding with a laser beam. Described models of a laser vibrometer illustrate the principle of the system. The results of the experiments illustrated the performance of the proposed method. The proposed system of laser control helps to raise the level of reliability of man-made systems (taking into account the development of real dynamic situations).
