Description

technical field [0001] The invention belongs to the field of Raman spectrum imaging, in particular to a Raman spectrum imaging resolution plate and a preparation method thereof. Background technique [0002] Raman spectroscopy is a physical phenomenon produced by the energy exchange between matter with a specific microstructure and motion state and photons during the interaction between light and matter. Raman spectroscopy belongs to molecular vibration spectroscopy, which can reflect the characteristic structure of molecules. Different substances have specific Raman spectra due to their unique microstructure and motion state, which makes Raman spectroscopy have the ability to identify molecular fingerprints. Because the intensity, polarization, frequency and other characteristics of Raman spectrum carry rich material structure information, the detection and imaging technology based on Raman spectrum is widely used in many research fields such as materials, petroleum, chemi...
