Name of spectral technology project

The name of the spectrum technology project includes the development of broadband ultra-fast spectrum in-situ measurement system under high temperature and high pressure, the development and application of high-precision terahertz optical comb imager, the rare cell sorting system of multicolor Raman spectrum microfluidic chip Qualcomm, the rare cell sorting system of multicolor Raman spectrum microfluidic chip Qualcomm, the development of spectrum system suitable for metal/metalloid speciation analysis of living systems, and the development of femtosecond time-resolved infrared absorption spectrum device.

The above spectral projects are the announcement of the evaluation results of the projects applied by the National Natural Science Foundation of China 202 1. Among them, there are 83 national major research instrument development projects (free application), and many of the 83 projects involve spectral instruments, including infrared, Raman, terahertz, hyperspectral and ultrafast spectra.

Brief introduction of spectral technology:

Spectrum is a pattern in which polychromatic light is divided by dispersion system and monochromatic light scattered by color is arranged in wavelength order, which is called spectrum. The largest visible part of the spectrum is the visible part of the electromagnetic spectrum, and the electromagnetic radiation within this wavelength range is called visible light. The spectrum does not contain all colors that can be distinguished by human vision, such as brown and pink.

Light wave is the electromagnetic radiation produced by electrons in the process of atomic motion. The motion of electrons in atoms of various substances is different, so the light waves emitted are also different. It is of great theoretical and practical significance to study the light emission and absorption of different substances, and it has become a special subject-spectroscopy. The infrared absorption spectrum of molecules is generally used to study the vibration spectrum and rotation spectrum of molecules, in which the molecular vibration spectrum has always been the main research topic.
