Title: Innovations of Jiawei Yang

Introduction

Jiawei Yang is a prominent inventor based in Beijing, China. He has made significant contributions to the field of optical technology, holding three patents that showcase his innovative approach to micro spectrum chips and artificial neural networks.

Latest Patents

One of his latest patents is a micro spectrum chip based on units of different shapes. This micro spectrum chip includes a CIS wafer and an optical modulation layer. The optical modulation layer consists of several micro-nano structure units arranged on the surface of a photosensitive area of the CIS wafer. Each micro-nano structure unit includes a plurality of micro-nano structure arrays, with different micro-nano structure arrays being two-dimensional gratings composed of internal units of various shapes. This design fully utilizes the degree of freedom of 'shape' to achieve a rich modulation effect on incident light.

Another notable patent is the optical artificial neural network intelligent chip, along with its preparation method and intelligent processing apparatus. In this invention, the optical filter layer serves as the input layer of the artificial neural network, while the image sensor acts as the linear layer. The filtering effect of the optical filter layer on the incident light functions as the connection weight from the input layer to the linear layer. This innovative approach eliminates the need for complicated signal processing and algorithm processing in subsequent artificial neural network intelligent processing.
