Advances in novel spectral techniques based on metasurface and computational reconstruction
This paper aims to explore the latest research progress in spectroscopic technology and introduce the cutting-edge directions in the field of spectroscopic analysis,represented by metasurface spectrometers and computa-tional reconstruction spectroscopic techniques.Firstly,the paper introduces the principle of metasurface technology,ana-lyzes the advantages of lightweight and ultra-compact metasurface spectrometer,expounds the research status of represen-tative metasurface spectrometers such as folding metasurface spectrometer and multi-focus metasurface spectrometer,and discusses the application prospect of metasurface spectrometer in the fields of disease diagnosis,quality control and infor-mation processing.Next,the principle of computational reconstruction spectroscopy is described,the characteristics and research situation of waveguide,spatial,filter coded and detector coded computational reconstruction spectrometers are introduced,and the application potential of computational reconstruction spectrometers in spectrum analysis and chemi-cal research is discussed.Then,the principle and characteristics of metasurface hyperspectral imager based on free shape element and deep learning are introduced,and the advantages of combining metasurface and computational reconstruc-tion spectroscopy are discussed.Last,it is pointed out that the combination of metasurface and computational reconstruc-tion spectroscopy will promote the development of the spectrum measurement field to be more intelligent,portable and multi-functional.It is proposed that the spectral measurement technology can be developed more accurately and effi-ciently by optimizing spectral image reconstruction algorithm,encoder and photodetector design and manufacturing pro-cess in the future.
