AI Technical Summary
The existing positioning frame cannot accommodate modulators of different sizes, which means that it needs to be redesigned and manufactured when the size of the modulator changes, which is time-consuming, labor-intensive and costly.
An auxiliary positioning frame for a mini fiber-optic coupled acousto-optic modulator is used. The distance and position of the first and second positioning frames are adjusted by the cooperation of a double-threaded screw and a guide screw to adapt to the width and length of the modulator body. The modulator is fixed by a locking tongue and a return spring.
The positioning frame was adapted to accommodate modulators of different sizes, simplifying the installation process and reducing design and manufacturing costs.
