Abstract

A flexible hinge alignment mechanism of a high-power optical system is made of a flexible hinge, and may lead to a relatively weak region of the hinge to achieve elastic displacement or rotation under stress loading. Through movable actuators such as screws and springs, the area is precisely moved, and the function of accurate alignment is achieved. When the flexible hinge causes the structure to move relatively due to the applied forces, it must be ensured that the corresponding distribution of maximum stress needs to be below the yielding point of the material, thus ensuring the mechanism acts in a material's elastic region. The design is beneficial to optimize the design of the optical alignment mechanism.
