AI Technical Summary
Technical Problem
In microgravity environments, the focusing mechanisms of existing space cameras do not have tight contact between components, leading to inaccurate focusing or secondary defocusing, which affects image quality.
Method used
The lens barrel is used for primary focusing via an inner wall thread, and a linkage mechanism is used for secondary focusing and limiting. Precise focusing is achieved through threaded engagement and motor drive.
Benefits of technology
It enables precise focusing in microgravity environments, prevents secondary defocusing, and improves the imaging quality of the space camera.
