1. An optical zoom structure, comprising:
at least an amplifying set, comprising:
a first fixed focal set comprising a plurality of first optical lenses;a first liquid crystal lens,wherein the amplifying set resembles a diverging optical effect; at least a focusing set, comprising:
a second fixed focal set comprising a plurality of second optical lenses;a second liquid crystal lens,wherein the focusing set resembles a converging optical effect; and an image display region,
wherein the focusing set is disposed between the amplifying set and the image display region, the first liquid crystal lens and the second fixed focal set are disposed between the first fixed focal set and the second liquid crystal lens,wherein a first distance is the distance between the first fixed focal set and the first liquid crystal lens, a second distance is the distance between the first liquid crystal lens and the second fixed focal set, a third distance is the distance between the second fixed focal set and the second liquid crystal lens, and a fourth distance is the distance between the second liquid crystal lens and the image display region,wherein the first distance, the second distance, the third distance, and the forth distance are constant value,wherein a focal length of the first liquid crystal lens is changed by adjusting an applying voltage of the first liquid crystal lens, and a focal length of the second liquid crystal lens is changed by adjusting an applying voltage of the second liquid crystal lens. |
