Patent Images
1. A zoom function system, comprising:
- an upper lens assembly;
a lower lens assembly;
an upper actuator comprising;
one or more upper stationary elements;
a first upper translation element to translate along a first direction;
a second upper translation element to translate along a second direction perpendicular to the first direction; and
a third upper translation element to translate along a third direction perpendicular to the first and the second directions; and
a lower actuator comprising;
one or more lower stationary elements;
a first lower translation element to translate along the first direction;
a second lower translation element to translate along the second direction; and
a third lower translation element to translate along the third direction;
wherein the upper lens assembly is attached to the first upper translation element of the upper actuator and the lower lens assembly is attached to the first lower translation element of the lower actuator.

Abstract
A zoom function system is disclosed. The zoom function system includes an upper lens assembly, a lower lens assembly, an upper actuator, and a lower actuator. The upper and the lower actuators have stationary elements and movable elements. The upper lens assembly is attached to one of the movable elements of the upper actuator. The lower lens assembly is attached to one of the movable elements of the lower actuator. The zoom function system allows three degrees of freedoms of translational adjustments of lens assemblies and is capable of realigning the lens assemblies to improve the qualities of images.
