Interferometer Movable Mirror Support Structure for Tilt Reduction

The flexible member is divided into multiple segments or sections along its length. Each segment can bend independently or with different flexibility, allowing the member to accommodate movement while maintaining overall alignment. This segmentation prevents unequal bending that would cause tilting, as each segment distributes the bending stress more evenly.

Different sections of the flexible member are given different local properties, such as varying thickness, material composition, or structural reinforcement. This allows specific regions to be stiffer or more flexible as needed, ensuring that bending occurs in a controlled and equal manner across the member, preventing tilting of the movable frame.

The flexible member incorporates dynamic characteristics that allow it to adapt its stiffness during movement. The member can be designed with progressive engagement of support structures or variable geometry that provides flexibility during movement phases while maintaining stability during positioning phases, thus achieving both smooth movement and alignment stability.

An intermediary support structure or mechanism is introduced between the flexible member and the movable frame. This intermediary element acts as a mediator that smooths out the movement while the flexible member maintains its alignment function. The intermediary could be a guide mechanism, damping element, or controlled articulation point that decouples the movement function from the alignment function.
