Liquid crystal super surface spectral single pixel imaging system

This project aims to research and develop a spectral single pixel imaging system based on liquid crystal metasurface, involving the design and processing of liquid crystal metasurface devices and the integration of spectral analysis systems. Focus on the application of liquid crystal supersurface in spectral compression and reconstruction, using advanced numerical simulation technology and innovative process and experimental methods, the goal is to provide technical support for the industrialization of miniaturized spectrometers and spectral imaging systems. As an advanced measurement and analysis method, miniaturized spectral measurement technology has the advantages of high resolution, non-contact, low cost and flexible deployment. It has potential applications in environmental protection, industrial monitoring and sorting, agricultural remote sensing, biological medicine, geological exploration, food detection, scientific research and development and many other fields.

 

This project innovatively proposes the near-infrared computational spectral reconstruction scheme of liquid crystal super-surface, explores the error mechanism of liquid crystal super-surface device modeling and simulation, studies and improves the coupling problem of liquid crystal and super-surface, and improves the one-to-many problem of compression reconstruction.

-project is based on liquid crystal super-surface device research and development technology, which can work stably in the 1500-1630nm band, with a sampling interval of 0.5nm and a spectral resolution of 3nm.
