Tsinghua University chip research results

Tsinghua University chip research results: developed the world's first real-time hyperspectral imaging chip.

One, Tsinghua University Department of Electronic Engineering Professor Huang Yidong team of Associate Professor Cui Kaiyu led the students in the hyper-spectral imaging chip has made significant progress in the development of the world's first real-time hyper-spectral imaging chip, compared with the existing spectral detection technology has been realized from a single-point spectrometer to the leap of hyper-spectral imaging chip.

The second, the spectrum as a material fingerprint, spectral imaging can be obtained imaging field of view of each pixel point material components and content, for intelligent perception technology to open up a new dimension of information, in industrial automation, intelligent medical care, machine vision, and many other fields have a huge demand for applications. However, the traditional single-point spectrometer based on the principle of spectroscopy is bulky, and the existing spectral imaging technology can only adopt the mode of point-by-point and row-by-row scanning or wavelength scanning, which is unable to obtain the high-precision real-time spectral information of each pixel in the field of view scene.

Three, a hypersurface spectral imaging chip based on free-shape superatoms has been developed, which achieves superior spectral imaging performance. The results of measurement reconstruction of broad-spectrum light and narrow-spectrum light show that this hyperspectral imaging chip is capable of reconstructing broad-spectrum light with fidelity of more than 99% as well as wavelength resolution of 0.5 nm. This research work further enhances the performance of the hypersurface spectral imaging chip and promotes the development of future spectral imaging chips and their applications in real-time sensing.

Significance of chip research at Tsinghua University

I. Tsinghua University is not only a double first-class university in China, but also a first-class scientific research institution in China. Tsinghua University focuses on scientific research, and through unremitting efforts and fruitful scientific research achievements, outstanding results.

Two, and now, the field of chip research has been in many companies, universities, scientific research institutions set off a storm, which also includes Tsinghua University, are to make it an important research topic. Especially in the Chinese Academy of Sciences, national defense and other aspects of their research opportunities are greater.

Three, in order to break the situation of China's long-standing chip technology is limited by the situation, spectral technology has become the first Tsinghua University to carry out research and innovation goals. After painstaking research, Tsinghua University made a breakthrough in new chip technology. The importance of photolithography, so to speak, the producer of photolithography technology, will determine the direction of the development of the entire chip industry.
