Title: Xianchang Zhu: Innovator in Optical Technologies
Introduction
Xianchang Zhu is a prominent inventor based in Chengdu, China. He has made significant contributions to the field of optical technologies, holding a total of 3 patents. His work focuses on enhancing precision in imaging systems and photolithography processes.
Latest Patents
One of his latest patents is a three-dimensional dynamic adjustment and locking mechanism. This invention discloses a three-dimensional adjustment mechanism designed for precise adjustment of an optical element in high-resolution imaging systems. The mechanism includes three elastic adjustment members that are uniformly distributed to conduct both axial displacement and tilt adjustments of the optical element. These members are arranged at the bottom of the optical element and are configured to perform dynamic adjustments with high precision based on their deformations.
Another notable patent is a method for detecting the focal plane based on the grating Talbot effect. This method aims to detect the position of a silicon wafer in a photolithography machine in real time. It facilitates the adjustment of leveling and focal plane of the silicon wafer with high resolution. The detection system utilizes a phase change of 'self-image' generated by the grating Talbot effect, which is caused by the defocusing of the silicon wafer. This system is characterized by its simple structure, higher anti-interference capability, and excellent adaptation to the process.
