Title: Weijian Yang: Innovator in Metalens Technology and Fetal Oximetry

Introduction

Weijian Yang is a prominent inventor based in Berkeley, CA (US). He has made significant contributions to the fields of optics and medical technology. With a total of 3 patents, Yang's work focuses on advanced imaging systems and fetal monitoring techniques.

Latest Patents

Yang's latest patents include innovative technologies such as a metasurface, metalens, and metalens array with controllable angular field-of-view. This invention discloses a metalens that includes a substrate and a two-dimensional (2D) grid over the substrate, dividing it into a 2D array of meta-units. Each meta-unit is designed with an angular-dependent transmission or reflection coefficient that decreases with an increasing incident angle of illumination. The metalens effectively passes incident light at angles below a cutoff while rejecting light at greater angles, allowing for the construction of a larger metalens array.

Another notable patent is for transabdominal fetal oximetry based on frequency-modulated continuous-wave near-infrared spectroscopy. This technology measures time-resolved reflectance values of light signals from a maternal-fetal multilayer tissue structure. The system functions as an optical interferometer, utilizing two frequency-swept laser sources to detect optical properties in vascular tissues, generating a time-resolved reflectance curve from the collected light signals.
