Hongfei Wang is a notable inventor based in Guangdong, China. He has made significant contributions to the field of optical systems and ranging methods. With a total of 2 patents, his work showcases innovative approaches to technology.
Latest Patents
One of his latest patents is a large-aperture, high-pixel optical system and camera module used thereby. This optical system consists of six lenses arranged successively from its object side to its image side along its optic axis. The first lens features a convex surface facing the object side and a concave surface facing the image side. The third lens is biconcave, while the second and fifth lenses are biconvex. The fourth and sixth lenses each have a concave surface facing the object side and a convex surface facing the image side. The fifth and sixth lenses form a combined lens, and the optical system satisfies TTL/EFL ≤ 4.5. Additionally, a camera module utilizing this system is disclosed, emphasizing a simple structure due to the limited number of lenses used.
Another significant patent involves a ranging method and system related to topographic techniques. This method includes steps such as modulating a measured beam with a continuously changing frequency over time, emitting the modulated beam to a measured object, and receiving the reflected beam to convert it into measured signals. By comparing the frequencies of the modulated signal and the measured signals, the method determines the measured distance.
