Description

Technical Field

[0001] The present invention belongs to the technical field of planetary early life evolution analysis systems, and in particular relates to a planetary early life evolution analysis system based on spectral information fusion analysis. Background Art

[0002] The origin of life is an important stage in the evolution of the universe. Life first appeared in the primitive membrane, then evolved into cell membrane, primitive cells, cytoplasm differentiation, DNA macromolecule evolution, chromatin formation, further formed the nuclear region, and then evolved from prokaryotic cells to eukaryotic cells. The formation of cells and the evolution from prokaryotic cells to eukaryotic cells are accompanied by chemical and biological changes catalyzed by the long-term external environment, which is an important stage in the formation of primitive life. In this process, the external environment such as atmosphere, temperature, lightning, and water are important foundations. Among them, light under natural conditions, including sunlight and lightning, is a very important life inducer. It can promote the synthesis of amino acids and also catalyze the transformation of life groups such as purine nucleic acids. Its microscopic physical mechanism is the action of photons and life group molecules, which causes changes in the spatial configuration of molecules and the breaking of fragile chemical bonds, thereby causing a series of changes in life effects. While light catalyzes the transformation of life, it also causes the light expression of life groups, such as changes in absorption, reflection, luminescence, and scattering characteristics. The light expression of primitive life groups has different characteristics in different evolutionary processes, which can provide an important basis for the microscopic and fine detection of life evolution.

[0003] It can be seen that the analysis of the evolution of early planetary life based on photocatalysis and photoexpression is an important means to understand the evolution of life formation and variation in the pre-biochemical period, but pure natural light makes this research process extremely long. An optional means to accelerate the research process is to use the current laser light source to photocatalyze the observed samples based on the properties of natural light. The analysis of the evolution of early planetary life through the combination of photocatalysis and photoexpression is very necessary for the analysis of the evolution of biological or life formation and variation. Summary of the invention

[0056] The output wavelength of the UV tunable filter 5 is set to the shortest wavelength. The motor controller 43 controls the optical expression detection subsystem 38 to rotate along the electric guide rail 37, so that the UV pulse laser is focused on the secondary stock solution 30 in the first detection window 35 for optical expression detection. The Raman fiber spectrometer 7 and the fluorescence fiber spectrometer 16 reflect the Raman and fluorescence spectrum information of the molecular composition and spatial conformation of the secondary stock solution 30.

[0057] The motor controller 43 controls the optical expression detection subsystem 38 to rotate along the electric guide rail 37, so that the ultraviolet pulse laser is focused on the mixed gas 29 in the first detection window 35 for optical expression detection. The Raman fiber spectrometer 7 and the fluorescence fiber spectrometer 16 reflect the Raman and fluorescence spectrum information of the molecular composition and spatial conformation of the mixed gas 29.

[0058] The optical expression detection subsystem of the present invention adopts ultraviolet resonance Raman selective excitation combined with ultraviolet fluorescence detection to characterize the differences in optical expression of life groups. The ultraviolet pulse laser is used as a common pump source in photocatalysis and optical expression, realizing the reuse of core components of the subsystem, reducing hardware resources in the optical system while achieving time synchronization of catalysis and expression detection.

[0059] The present invention provides a planetary early life evolution analysis system based on spectral information fusion analysis, which adopts a catalytic method that mainly uses strong pulse supercontinuum laser photocatalysis and is supplemented by high voltage discharge, cosmic rays, etc. It can be accelerated by extreme conditions and observe long processes such as life evolution through light expression in a limited time. In the photocatalytic process, the action of photons and life group molecules causes changes in the spatial configuration of molecules and the breaking of fragile chemical bonds, causing the light expression of life groups, such as changes in absorption, reflection, luminescence, and scattering characteristics.
