  • Optical zoom structure
    Patent number: 9684101
    Abstract: An optical zoom structure includes an amplifying set, a focusing set, and an image display region. The amplifying set resembles the diverging optical effect and includes a first fixed focal set and a first liquid crystal lens. The focusing set resembles a converging optical effect and includes a second fixed focal set and a second liquid crystal lens. 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. The first distance is from the first fixed focal set to the first liquid crystal lens. The second distance is from the first liquid crystal lens to the second fixed focal set. The third distance is from the second fixed focal set to the second liquid crystal lens. The fourth distance is from the second first liquid crystal lens to the image display region.
