Title: Innovations of Inventor Hung-Te Lee
Introduction
Hung-Te Lee is a prominent inventor based in Taipei, Taiwan. He has made significant contributions to the field of optical technology, holding a total of 5 patents. His work focuses on improving optical devices, particularly in the areas of zoom lenses and optical pickup heads.
Latest Patents
One of Hung-Te Lee's latest patents is an improved zoom lens. This innovation consists of a plurality of lens groups with different focal lengths. By adjusting the position of these lens groups, various zooming ratios can be achieved. This design not only enhances image resolution but also reduces costs by utilizing different lens materials. The lens groups feature a combination of focal lengths that include positive, negative, positive, and positive. Notably, the second and fourth lens groups are movable, which contributes to obtaining high-quality images.
Another significant patent is for a single surface diffractive element used in optical pickup heads. This optical pickup device includes a lighting source, a condensing apparatus, a diffracting means, and a light detector. The light source generates a beam that interacts with the diffracting means, which has a center region and an outer region. As the light travels towards the optical storage medium, the main zero-order beam reads the information on the disk, while two sub-beams for track following are created from the outer region. The light detector consists of multiple elements that convert the reflected light into electronic signals containing the recorded information.
