Problems solved by technology

The currently disclosed three-dimensional optical deformation measurement device only provides a structural diagram of the measurement device and a simple installation method based on the optical fixing seat and the adjustment frame, and does not provide a dedicated precision installation device and method for each component
The simple installation method based on the optical fixed seat and the adjustment frame can realize the installation and adjustment of the various parts of the three-dimensional optical deformation measurement device, but it is difficult to achieve good temperature stability and structural stability when the stress state changes, resulting in temperature changes. Or the deformation measurement accuracy drops significantly under the condition of external force change

Description

technical field [0001] The invention belongs to the technical field of optical deformation measurement, and in particular relates to an installation device and method of an arc-second-level three-dimensional optical deformation measurement device. Background technique [0002] Optical deformation measurement technology can be widely used in large-scale motion platform deformation measurement and high-precision attitude reference transmission, etc. It has the advantages of high measurement accuracy, direct measurement, and good stability. Most of the current optical deformation measurement is realized by the collimated optical path method. In practical application, due to the influence of factors such as changes in environmental temperature and force state changes caused by the movement of the carrier, the final deformation measurement accuracy is closely related to the specific precision installation device and method.
